{{short description|Form of government}}
A '''parliamentary system''', or '''parliamentary democracy''', is a [[Philosophy:System|system]] of [[Social:Democracy|democratic]] [[Social:Government|government]] where the [[Social:Head of government|head of government]] (who may also be the [[Social:Head of state|head of state]]) derives their [[Social:Election|democratic]] legitimacy from their ability to command the support ("confidence") of the [[Social:Legislature|legislature]], typically a [[Social:Parliament|parliament]], to which they are accountable.

In a parliamentary system, the [[Social:Head of state|head of state]] and [[Social:Head of government|head of government]] are usually two separate positions, with the head of state serving as a ceremonial figurehead with little if any power, while all of the real political power is vested in the head of government. This is in contrast to a presidential system, which features a president who is usually both the head of state and the head of government and, most importantly, does not derive their legitimacy from the legislature.

Countries with parliamentary systems may be [[Social:Constitutional monarchy|constitutional monarchies]], where a [[Social:Monarch|monarch]] is the head of state while the head of government is almost always a member of parliament, or [[Social:Parliamentary republic|parliamentary republics]], where a mostly ceremonial president is the head of state while the head of government is regularly from the legislature. In a few parliamentary republics, among some others, the head of government is also head of state, but is elected by and is answerable to parliament. In bicameral parliaments, the head of government is generally, though not always, a member of the lower house.

Parliamentarianism is the dominant form of government in Europe, with 32 of its 50 sovereign states being parliamentarian. It is also common across the Caribbean, being the form of government of 10 of its 13 island states, and in Oceania. Elsewhere in the world, parliamentary governments are less common, but they are distributed through all continents, most often in former colonies of the [[Place:British Empire|British Empire]] that subscribe to a particular brand of parliamentarianism known as the [[Social:Westminster system|Westminster system]].
==History==
{{Further|Social:History of parliamentarism}}

Since ancient times, when societies were tribal, there were councils or a headman whose decisions were assessed by village elders. Eventually, these councils slowly evolved into the modern parliamentary system.

The first [[Social:Parliament|parliament]]s date back to Europe in the Middle Ages: specifically in 1188 Alfonso IX, King of Leon (Spain) convened the three states in the Cortes of León.<ref>{{cite web|url=http://www.unesco.org/new/en/communication-and-information/memory-of-the-world/register/full-list-of-registered-heritage/registered-heritage-page-8/the-decreta-of-leon-of-1188-the-oldest-documentary-manifestation-of-the-european-parliamentary-system/|title=The Decreta of León of 1188 – The oldest documentary manifestation of the European parliamentary system|publisher=UNESCO Memory of the World|date=2013|access-date=21 May 2016|archive-date=24 June 2016|archive-url=https://web.archive.org/web/20160624133501/http://www.unesco.org/new/en/communication-and-information/memory-of-the-world/register/full-list-of-registered-heritage/registered-heritage-page-8/the-decreta-of-leon-of-1188-the-oldest-documentary-manifestation-of-the-european-parliamentary-system/|url-status=live}}</ref><ref>John Keane: ''The Life and Death of Democracy'', London 2009, 169–176.</ref> The Corts of Catalonia were the first parliament of Europe that officially obtained the power to pass legislation, apart from the custom.<ref>{{cite book |last1=Sánchez |first1=Isabel |title=La Diputació del General de Catalunya (1413-1479) |date=2004 |publisher=Institut d'Estudis Catalans |location=Barcelona |isbn=9788472837508 |page=92}}</ref> An early example of parliamentary government developed in today's Netherlands and Belgium during the Dutch revolt (1581), when the sovereign, legislative and executive powers were taken over by the States General of the Netherlands from the monarch, King Philip II of Spain.{{Citation needed|date=September 2016}} The modern concept of parliamentary government emerged in the [[Place:Kingdom of Great Britain|Kingdom of Great Britain between 1707 and 1800]] and its contemporary, the Parliamentary System in Sweden between 1721 and 1772.

The rising commercial class that had supported the Tudor monarchy in the 16th century led the revolutionary battle in the 17th, and succeeded in establishing the supremacy of Parliament and, eventually, of the House of Commons. What emerged as the distinctive feature of modern constitutionalism was not the insistence on the idea that the king is subject to law (although this concept is an essential attribute of all constitutionalism). This notion was already well established in the Middle Ages. What was distinctive was the establishment of effective means of political control whereby the rule of law might be enforced. Modern constitutionalism was born with the political requirement that representative government depended upon the consent of citizen subjects.... However, as can be seen through provisions in the 1689 Bill of Rights, the English Revolution was fought not just to protect the rights of property (in the narrow sense) but to establish those liberties which liberals believed essential to human dignity and moral worth. The "rights of man" enumerated in the English Bill of Rights gradually were proclaimed beyond the boundaries of England, notably in the American Declaration of Independence of 1776 and in the French Declaration of the Rights of Man in 1789.|url-status=dead|archive-url=https://web.archive.org/web/20141024130317/http://www.ait.org.tw/infousa/zhtw/DOCS/Demopaper/dmpaper2.html|archive-date=24 October 2014}}</ref>

In the [[Place:Kingdom of Great Britain|Kingdom of Great Britain]], the monarch, in theory, chaired the cabinet and chose ministers. In practice, King George I's inability to speak English led to the responsibility for chairing cabinet to go to the leading minister, literally the ''[[Social:Prime minister|prime]]'' or first minister, Robert Walpole. The gradual democratisation of parliament with the broadening of the voting franchise increased parliament's role in controlling government, and in deciding whom the king could ask to form a government. By the 19th century, the Great Reform Act of 1832 led to parliamentary dominance, with its choice ''invariably'' deciding who was prime minister and the complexion of the government.<ref>{{cite web|title=The Institution of Prime Minister|url=https://history.blog.gov.uk/2012/01/01/the-institution-of-prime-minister/|publisher=Government of the United Kingdom|website = History of Government Blog|date=1 January 2012|first1= Andrew|last1=  Blick |first2= George|last2= Jones|archive-date=10 March 2016|archive-url=https://web.archive.org/web/20160310152512/https://history.blog.gov.uk/2012/01/01/the-institution-of-prime-minister/ |url-status=live}}</ref><ref>{{cite book|last1=Carter|first1=Byrum E.|title=Office of the Prime Minister|date=2015|orig-year=1955|publisher=Princeton University Press|isbn=9781400878260|chapter-url=https://books.google.com/books?id=ez7WCgAAQBAJ|chapter=The Historical Development of the Office of Prime Minister|access-date=6 June 2020|archive-date=19 August 2020|archive-url=https://web.archive.org/web/20200819062756/https://books.google.com/books?id=ez7WCgAAQBAJ|url-status=live}}</ref>

Other countries gradually adopted what came to be called the Westminster system of government,<ref>{{cite web |date=2 December 2013 |title=How the Westminster Parliamentary System was exported around the World |url=http://www.cam.ac.uk/research/features/how-the-westminster-parliamentary-system-was-exported-around-the-world |access-date=16 December 2013 |publisher=University of Cambridge}}</ref> with an executive answerable to the lower house of a bicameral parliament, and exercising, in the name of the head of state, powers nominally vested in the head of state – hence the use of phrases such as ''Her Majesty's government'' (in constitutional monarchies) or ''His Excellency's government'' (in [[Social:Parliamentary republic|parliamentary republic]]s).<ref>{{cite book |last1=Seidle |first1=F.

[[Social:Democracy|Democracy]] and parliamentarianism became increasingly prevalent in Europe in the years after [[Social:World War I|World War I]], partially imposed by the democratic victors,{{how|date=November 2019}} the United States, Great Britain and France, on the defeated countries and their successors, notably Germany's Weimar Republic and the First Austrian Republic. Nineteenth-century urbanisation, the [[History:Industrial Revolution|Industrial Revolution]] and [[Philosophy:Modernism|modernism]] had already made the parliamentarist demands of the [[Social:Classical radicalism|Radicals]] and the emerging movement of [[Philosophy:Social democracy|social democrats]] increasingly impossible to ignore; these forces came to dominate many states that transitioned to parliamentarism, particularly in the [[Place:French Third Republic|French Third Republic]] where the Radical Party and its centre-left allies dominated the government for several decades. However, the rise of [[Social:Fascism|Fascism]] in the 1930s put an end to parliamentary democracy in Italy and Germany, among others.

After the Second World War, the defeated fascist Axis powers were occupied by the victorious Allies. In those countries occupied by the Allied democracies (the {{wipe|United States}}, {{wipe|United Kingdom}}, and {{wipe|France}}) parliamentary constitutions were implemented, resulting in the parliamentary constitutions of Italy and West Germany (now all of Germany) and the 1947 Constitution of Japan. The experiences of the war in the occupied nations where the legitimate democratic governments were allowed to return strengthened the public commitment to parliamentary principles; in {{wipe|Denmark}}, a new constitution was written in 1953, while a long and acrimonious debate in Norway resulted in no changes being made to that country's strongly entrenched democratic constitution.

==Characteristics==
{{Further|Social:Parliamentary procedure}}
A parliamentary system may be either [[Social:Bicameralism|bicameral]], with two chambers of parliament (or houses) or unicameral, with just one parliamentary chamber. A bicameral parliament usually consists of a directly elected lower house with the power to determine the executive government, and an upper house which may be appointed or elected through a different mechanism from the lower house.

===Types===
Scholars of democracy such as Arend Lijphart distinguish two types of parliamentary democracies: the Westminster and Consensus systems.<ref>{{cite book| last=Lijphart |first=Arend |year=1999 |title=Patterns of democracy |location=New Haven |publisher=Yale University Press}}</ref>

====Westminster system====
[[File:Houses.of.parliament.overall.arp.jpg|thumb|right|upright=0.9|The Palace of Westminster in London, United Kingdom. The Westminster system originates from the British Houses of Parliament.]]
* The [[Social:Westminster system|Westminster system]] is usually found in the [[Organization:Commonwealth of Nations|Commonwealth of Nations]] and countries which were influenced by the British political tradition.<ref>{{cite book|editor1-last=Arjomand|editor1-first=Saïd Amir|title=Constitutionalism and political reconstruction|date=2007|publisher=Brill|isbn=978-9004151741|pages=92–94|chapter-url=https://books.google.com/books?id=kYmmnYKEvE0C&pg=PA94|author1=Julian Go|chapter=A Globalizing Constitutionalism?, Views from the Postcolony, 1945–2000|access-date=6 June 2020|archive-date=1 August 2020|archive-url=https://web.archive.org/web/20200801015306/https://books.google.com/books?id=kYmmnYKEvE0C&lpg=PA93&pg=PA94|url-status=live}}</ref><ref>{{cite web|title=How the Westminster Parliamentary System was exported around the World|url=http://www.cam.ac.uk/research/features/how-the-westminster-parliamentary-system-was-exported-around-the-world|publisher=University of Cambridge|access-date=16 December 2013|date=2 December 2013|archive-date=16 December 2013|archive-url=https://web.archive.org/web/20131216190945/http://www.cam.ac.uk/research/features/how-the-westminster-parliamentary-system-was-exported-around-the-world|url-status=live}}</ref><ref>{{cite book|last1=Seidle|first1=F.

Some parliaments in this model are elected using a plurality voting system (first past the post), such as the United Kingdom, Canada, India and Malaysia, while others use some form of [[Social:Proportional representation|proportional representation]], such as Ireland and New Zealand. The Australian House of Representatives is elected using instant-runoff voting, while the Senate is elected using proportional representation through [[Social:Single transferable vote|single transferable vote]]. Regardless of which system is used, the voting systems tend to allow the voter to vote for a named candidate rather than a closed list. Most Westminster systems employ strict monism, where Ministers must be members of Parliament simultaneously; while some Westminster systems, such as Bangladesh,<ref>{{Cite web|title=The Constitution of the People's Republic of Bangladesh|url=http://bdlaws.minlaw.gov.bd/act-details-367.html|access-date=2023-02-08|website=bdlaws.minlaw.gov.bd|at=Article 56}}</ref>{{secondary source needed|date=January 2024}} permit the appointment of extra-parliamentary Ministers, and others (such as Jamaica) allow outsiders to be appointed to the Ministry through an appointed Upper House, although a majority of Ministers (which, by necessity, includes the Prime Minister) must come from within (the lower house of) Parliament.

====Consensus system====
[[File:Berlin reichstag CP.jpg|thumb|right|upright=0.9|The Reichstag Building in Berlin, Germany. The Consensus system is used in most Western European countries.]]
* The Western European parliamentary model (e.g., Spain, Germany) tends to have a more consensual debating system and usually has semi-circular debating chambers. Consensus systems have more of a tendency to use [[Social:Proportional representation|proportional representation]] with open party lists than the Westminster Model legislatures. The committees of these Parliaments tend to be more important than the plenary chamber. Most Western European countries do not employ strict monism, and allow extra-parliamentary ministers as a matter of course. The Netherlands, Slovakia and Sweden outright implement the principle of [[Dualism (politics)|dualism]] as a form of [[Philosophy:Separation of powers|separation of powers]], where Members of Parliament have to resign their place in Parliament upon being appointed (or elected) minister.

===Election of the head of government===

Implementations of the parliamentary system can also differ as to how the prime minister and government are appointed and whether the government needs the explicit approval of the parliament, rather than just the absence of its disapproval. Some countries such as India also require the prime minister to be a member of the legislature, though in other countries this only exists as a convention.

* ''' The head of state appoints a prime minister who will likely have majority support in parliament'''. While in the majority of cases prime ministers in the [[Social:Westminster system|Westminster system]] are the leaders of the largest party in parliament, technically the appointment of the prime minister is a prerogative exercised by the head of state (be it the monarch, the governor-general, or the president). This system is used in:

** {{flag|Australia}}
** {{flag|Canada}}
** {{flag|Malaysia}}
** {{flag|New Zealand}}
** {{flag|United Kingdom}}

* ''' The head of state appoints a prime minister who must gain a vote of confidence within a set time.''' This system is used in:

** {{flag|Italy}}
** {{flag|Thailand}}

* ''' The head of state appoints the leader of the political party holding a plurality of seats in parliament as prime minister'''. For example, in Greece, if no party has a majority, the leader of the party with a plurality of seats is given an ''exploratory mandate'' to receive the confidence of the parliament within three days. If said leader fails to obtain the confidence of parliament, then the leader of the ''second''-largest party is given the ''exploratory mandate''. If that fails, then the leader of the ''third''-largest political party is given the ''exploratory mandate'', and so on. This system is used in:

** {{flag|Greece}}

* ''' The head of state ''nominates'' a candidate for prime minister who is then submitted to parliament for approval before appointment.''' Example: Spain, where the King sends a proposal to the Congress of Deputies for approval. Also, Germany where under the German Basic Law (constitution) the Bundestag votes on a candidate nominated by the federal president. In these cases,{{Citation needed|date=July 2019}} parliament can choose another candidate who then would be appointed by the head of state. This system is used in:

** {{flag|Germany}}
** {{flag|Spain}}

* ''' Parliament ''nominates'' a candidate whom the head of state is constitutionally obliged to appoint as prime minister.''' Example: Japan, where the Emperor appoints the Prime Minister on the nomination of the National Diet. Also Ireland, where the President of Ireland appoints the Taoiseach on the nomination of Dáil Éireann. This system is used in:

** {{flag|Ireland}}
** {{flag|Japan}}

* '''A public officeholder (other than the head of state or their representative) ''nominates'' a candidate, who, if approved by parliament, is appointed as prime minister.''' Example: Under the Swedish Instrument of Government (1974), the power to appoint someone to form a government has been moved from the monarch to the Speaker of Parliament and the parliament itself. The speaker nominates a candidate, who is then elected to prime minister (''statsminister'') by the parliament if an absolute majority of the members of parliament does not vote against the candidate (i.e. they can be elected even if more members of parliament vote ''No'' than ''Yes).'' This system is used in:

** {{flag|Sweden}}

* '''Direct election by popular vote.''' Example: Israel, 1996–2001, where the prime minister was elected in a general election, with no regard to political affiliation, and whose procedure can also be described as of a [[Social:Semi-parliamentary system|semi-parliamentary system]].<ref name="Pouvoirs">{{cite magazine |last=Duverger |first=Maurice |date=September 1996 |title=Les monarchies républicaines |trans-title=The crowned republics |url=http://www.revue-pouvoirs.fr/IMG/pdf/78Pouvoirs_p107-120_monarchies_republicaines.pdf |language=fr |magazine=Pouvoirs, revue française d'études constitutionnelles et politiques |location=Paris |publisher=Éditions du Seuil |issn=0152-0768 |isbn=2-02-030123-7 |issue=78 |pages=107–120 |access-date=10 September 2016 |archive-date=1 October 2018 |archive-url=https://web.archive.org/web/20181001151614/https://revue-pouvoirs.fr/IMG/pdf/78Pouvoirs_p107-120_monarchies_republicaines.pdf |url-status=dead }}</ref><ref name="Forms">{{cite book |last1=Frosini |first1=Justin Orlando |year=2008 |editor-last=Ferrari |editor-first=Giuseppe Franco |title=Forms of State and Forms of Government |url=https://books.google.com/books?id=GFBPlYjuJYsC |publisher=Giuffrè Editore |pages=54–55 |isbn=9788814143885 |access-date=13 November 2016 |via=[[Google Books]] |archive-date=19 August 2020 |archive-url=https://web.archive.org/web/20200819092351/https://books.google.com/books?id=GFBPlYjuJYsC |url-status=live }}</ref> This system was used in:

===Power of dissolution and call for election===
Furthermore, there are variations as to what conditions exist (if any) for the government to have the right to dissolve the parliament:
* In some countries, especially those operating under a [[Social:Westminster system|Westminster system]], such as the United Kingdom, Denmark, Malaysia, Australia and New Zealand, the prime minister has the ''de facto'' power to call an election, at will. In Spain, the prime minister is the only person with the ''de jure'' power to call an election, granted by Article 115 of the Constitution.
* In Israel, parliament may vote to dissolve itself in order to call an election, or the prime minister may call a snap election with presidential consent if his government is deadlocked. A non-passage of the budget automatically calls a snap election.
* Other countries only permit an election to be called in the event of a vote of no confidence against the government, a supermajority vote in favour of an early election or a prolonged deadlock in parliament. These requirements can still be circumvented. For example, in Germany in 2005, Gerhard Schröder deliberately allowed his government to lose a confidence motion, in order to call an early election.
* In Sweden, the government may call a snap election at will, but the newly elected Riksdag is only elected to fill out the previous Riksdag's term. The last time this option was used was in 1958.
* In Greece, a general election is called if the Parliament fails to elect a new head of state when his or her term ends. In January 2015, this constitutional provision was exploited by [[Social:Syriza|Syriza]] to trigger a snap election, win it and oust rivals New Democracy from power.
* In Italy the government has no power to call a snap election. A snap election can only be called by the head of state, following a consultation with the presidents of both houses of parliament.
* Norway is unique among parliamentary systems in that the Storting always serves the whole of its four-year term.
* In Australia, under certain, unique conditions, the prime minister can request the Governor General to call for a double dissolution, whereby all rather than only half of the Senate, is dissolved – in effect electing all of the Parliament simultaneously.

The parliamentary system can be contrasted with a [[Social:Presidential system|presidential system]] which operates under a stricter separation of powers, whereby the executive does not form part of—nor is appointed by—the parliamentary or legislative body. In such a system, parliaments or congresses do not select or dismiss heads of government, and governments cannot request an early dissolution as may be the case for parliaments (although the parliament may still be able to dissolve itself, as in the case of [[Place:Cyprus|Cyprus]]). There also exists the [[Social:Semi-presidential system|semi-presidential system]] that draws on both presidential systems and parliamentary systems by combining a powerful president with an executive responsible to parliament: for example, the French Fifth Republic.

Parliamentarianism may also apply to regional and local governments. An example is [[Place:Oslo|Oslo]] which has an executive council (Byråd) as a part of the parliamentary system. The devolved nations of the United Kingdom are also parliamentary and which, as with the UK Parliament, may hold early elections – this has only occurred with regards to the Northern Ireland Assembly in 2017 and 2022.

===Anti-defection law===

A few parliamentary democratic nations such as India, Pakistan and Bangladesh have enacted laws that prohibit floor crossing or switching parties after the election. Under these laws, elected representatives will lose their seat in the parliament if they go against their party in votes.<ref>{{Cite web |url=http://prsindia.org/uploads/media/Note%20on%20Anti-Defection.pdf |title=The Anti-Defection Law – Intent and Impact Background Note for the Conference on Effective Legislatures |access-date=16 December 2019 |archive-date=19 August 2019 |archive-url=https://web.archive.org/web/20190819113945/http://www.prsindia.org/uploads/media/Note%20on%20Anti-Defection.pdf |url-status=live }}</ref><ref>{{Cite web|url=http://www.legalservicesindia.com/article/1937/Anti-defection-law-the-challenges.html|title=Anti-defection law the challenges|website=legalservicesindia.com|access-date=16 December 2019|archive-date=2 December 2019|archive-url=https://web.archive.org/web/20191202021958/http://www.legalservicesindia.com/article/1937/Anti-defection-law-the-challenges.html|url-status=live}}</ref><ref>{{Cite journal|url=http://nujslawreview.org/wp-content/uploads/2015/02/kartik-khanna-and-dhvani-shah.pdf|title=ANTI-DEFECTION LAW: A DEATH KNELL FOR PARLIAMENTARY DISSENT?|journal=NUJS Law Review|date=Mar 2012|access-date=15 May 2016|url-status=dead|archive-url=https://web.archive.org/web/20160528062743/http://nujslawreview.org/wp-content/uploads/2015/02/kartik-khanna-and-dhvani-shah.pdf|archive-date=28 May 2016}}</ref>

In the UK parliament, a member is free to cross over to a different party. In Canada and Australia, there are no restraints on legislators switching sides.<ref>{{Cite web|url=https://barandbench.com/anti-defection-laws-in-india-its-flaws-and-its-falls/|title=[Columns] Anti-Defection Laws in India: Its flaws and its falls|date=1 August 2019}}</ref> In New Zealand, waka-jumping legislation provides that MPs who switch parties or are expelled from their party may be expelled from Parliament at the request of their former party's leader.

=== Parliamentary sovereignty ===
{{Further|Social:Parliamentary sovereignty}}
A few parliamentary democracies such as the {{wipe|United Kingdom}} and [[Earth:New Zealand|New Zealand]] have weak or non-existent checks on the legislative power of their Parliaments,<ref>{{Cite web |date=27 October 2022 |title=UK Parliament glossary |url=https://www.parliament.uk/site-information/glossary/parliamentary-sovereignty/ |url-status=live |archive-url=https://web.archive.org/web/20220928161907/https://www.parliament.uk/site-information/glossary/parliamentary-sovereignty/ |archive-date=28 September 2022 |access-date=27 October 2022 |website=UK Parliament}}</ref><ref>{{Cite web |date=20 January 2016 |title=Our system of government |url=https://www.parliament.nz/en/visit-and-learn/how-parliament-works/our-system-of-government/ |url-status=live |archive-url=https://web.archive.org/web/20221017113130/https://www.parliament.nz/en/visit-and-learn/how-parliament-works/our-system-of-government/ |archive-date=17 October 2022 |access-date=27 October 2022 |publisher=New Zealand Parliament}}</ref> where any newly approved Act shall take precedence over all prior Acts. All laws are equally unentrenched, wherein judicial review may not outright annul nor amend them, as frequently occurs in other parliamentary systems like Germany. Whilst the head of state for both nations (Monarch, and or Governor General) has the de jure power to withhold [[Social:Royal assent|assent]] to any bill passed by their Parliament, this check has not been exercised in Britain since the 1708 Scottish Militia Bill.

Whilst both the UK and New Zealand have some Acts or parliamentary rules establishing [[Social:Supermajority|supermajorities]] or additional legislative procedures for certain legislation, such as previously with the Fixed-term Parliaments Act 2011 (FTPA), these can be bypassed through the enactment of another that amends or ignores these supermajorities away, such as with the Early Parliamentary General Election Act 2019 – bypassing the 2/3rd supermajority required for an early dissolution under the FTPA<ref>{{Cite web |date=26 November 2021 |title=Fixed-term Parliament Act 2011 |url=https://commonslibrary.parliament.uk/research-briefings/sn06111/ |url-status=live |archive-url=https://web.archive.org/web/20221021190612/https://commonslibrary.parliament.uk/research-briefings/sn06111/ |archive-date=21 October 2022 |access-date=27 October 2022 |website=UK Parliament}}</ref> -, which enabled the early dissolution for the 2019 general election.

=== Metrics ===
Parliamentarism metrics allow a quantitative comparison of the strength of parliamentary systems for individual countries. One parliamentarism metric is the Parliamentary Powers Index.<ref>{{Cite book|last1=Fish|first1=M. Steven|url=https://www.cambridge.org/core/books/handbook-of-national-legislatures/E069CD547EBAA4FE7D241E115C18664E|title=The Handbook of National Legislatures: A Global Survey|last2=Kroenig|first2=Matthew|date=2009|publisher=Cambridge University Press|isbn=978-0-521-51466-8|location=Cambridge|doi=10.1017/cbo9780511575655}}</ref>

==Advantages==
=== Adaptability ===
Parliamentary systems like that found in the United Kingdom are widely considered to be more flexible, allowing a rapid change in legislation and policy as long as there is a stable majority or coalition in parliament, allowing the government to have 'few legal limits on what it can do'<ref name = 0745-1253>{{Cite journal|last=Weaver|first=R. Kent|date=1985|title=Are Parliamentary Systems Better?|journal=The Brookings Review|volume=3|issue=4|pages=16–25|doi=10.2307/20079894|issn=0745-1253|jstor=20079894}}</ref> When combined with first-past-the-post voting, this system produces the classic "Westminster model" with the twin virtues of strong but responsive party government.<ref>{{Cite journal|last=Norris|first=Pippa|s2cid=144867316|date=1995 |title= The Politics of Electoral Reform in Britain|journal= International Political Science Review|volume=16|issue=1|pages=65–78 |issn= 0192-5121 |jstor=1601169|doi=10.1177/019251219501600105}}</ref> This electoral system providing a strong majority in the House of Commons, paired with the [[Social:Fusion of powers|fused power system]] results in a particularly powerful government able to provide change and 'innovate'.<ref name = 0745-1253/>

=== Scrutiny and accountability ===
The United Kingdom's fused power system is often noted to be advantageous with regard to accountability. The centralised government allows for more transparency as to where decisions originate from, this contrasts with the American system with Treasury Secretary C. Douglas Dillon saying "the president blames Congress, the Congress blames the president, and the public remains confused and disgusted with government in Washington".<ref>{{Cite book|url=http://archive.org/details/constitutionalre00sund_1|title=Constitutional reform and effective government|last=Sundquist|first=James L.|date=1992|publisher=Washington, D.C.: Brookings Institution|others=Internet Archive}}</ref> Furthermore, ministers of the U.K. cabinet are subject to weekly Question Periods in which their actions/policies are scrutinised; no such regular check on the government exists in the U.S. system.

=== Distribution of power ===
A 2001 [[Organization:World Bank|World Bank]] study found that parliamentary systems are associated with less corruption.<ref>{{cite book |last1=Lederman |first1=Daniel |title=Accountability and Corruption: Political Institutions Matter |series=Policy Research Working Papers |date=November 2001 |publisher=World Bank |page=27 |doi=10.1596/1813-9450-2708 |url=https://elibrary.worldbank.org/doi/abs/10.1596/1813-9450-2708}}</ref>

=== Calling of elections ===

In his 1867 book ''The English Constitution'', Walter Bagehot praised parliamentary governments for producing serious debates, for allowing for a change in power without an election, and for allowing elections at any time. Bagehot considered fixed-term elections such as the four-year election rule for presidents of the United States to be unnatural, as it can potentially allow a president who has disappointed the public with a dismal performance in the second year of his term to continue on until the end of his four-year term. Under a parliamentary system, a prime minister that has lost support in the middle of his term can be easily replaced by his own peers with a more popular alternative, as the Conservative Party in the UK did with successive prime ministers David Cameron, Theresa May, Boris Johnson, Liz Truss, and Rishi Sunak.

Although Bagehot praised parliamentary governments for allowing an election to take place at any time, the lack of a definite election calendar can be abused. Under some systems, such as the British, a ruling party can schedule elections when it believes that it is likely to retain power, and so avoid elections at times of unpopularity. (From 2011, election timing in the UK was partially fixed under the Fixed-term Parliaments Act 2011, which was repealed by the Dissolution and Calling of Parliament Act 2022.) Thus, by a shrewd timing of elections, in a parliamentary system, a party can extend its rule for longer than is feasible in a presidential system. This problem can be alleviated somewhat by setting fixed dates for parliamentary elections, as is the case in several of Australia's state parliaments. In other systems, such as the Dutch and the Belgian, the ruling party or coalition has some flexibility in determining the election date. Conversely, flexibility in the timing of parliamentary elections can avoid periods of legislative gridlock that can occur in a fixed period presidential system. In any case, voters ultimately have the power to choose whether to vote for the ruling party or someone else.

== Disadvantages<!--'Anti-parliamentarianism' and 'Anti-parliamentarism' redirect here--> ==
===Incomplete separation of power===
{{Undue weight|date=January 2024|to=this section by making broad generalisations based solely on one citation, and looking solely at one country's parliamentary system}}
According to Arturo Fontaine, parliamentary systems in Europe have yielded very powerful heads of government which is rather what is often criticized about presidential systems. Fontaine compares United Kingdom's Margaret Thatcher to the United States' Ronald Reagan noting the former head of government was much more powerful despite governing under a parliamentary system.<ref name=Fontaine2021>{{Cite news|title=Arturo Fontaine: "Si se estableciera el semipresidencialismo, a poco andar el pueblo sentiría que ha sido engañado"|url=https://www.emol.com/noticias/Nacional/2021/11/05/1037461/cronica-constitucional-arturo-fontaine-semipresidencialismo.html|last=Valenzuela Manguini|first=Álvaro|date=2021-11-05|access-date=2021-11-07|work=Emol|language=Spanish}}</ref> The rise to power of Viktor Orbán in Hungary has been claimed to show how parliamentary systems can be subverted.<ref name=Fontaine2021/> The situation in Hungary was according to Fontaine allowed by the deficient separation of powers that characterises parliamentary and semi-presidential systems.<ref name=Fontaine2021/> Once Orbán's party got two-thirds of the seats in Parliament in a single election, a [[Social:Supermajority|supermajority]] large enough to amend the Hungarian constitution, there was no institution that was able to balance the concentration of power.<ref name=Fontaine2021/> In a presidential system it would require at least two separate elections to create the same effect; the presidential election, and the legislative election, and that the president's party has the legislative supermajority required for constitutional amendments. Safeguards against this situation implementable in both systems include the establishment of an upper house or a requirement for external ratification of constitutional amendments such as a [[Social:Referendum|referendum]]. Fontaine also notes as a warning example of the flaws of parliamentary systems that if the United States had a parliamentary system, Donald Trump, as head of government, could have dissolved the United States Congress.<ref name=Fontaine2021/>

=== Legislative flip-flopping ===
{{Undue weight|date=January 2024|to=by making broad generalisations but citing only one authority}}
The ability for strong parliamentary governments to push legislation through with the ease of fused power systems such as in the United Kingdom, whilst positive in allowing rapid adaptation when necessary e.g. the nationalisation of services during the world wars, in the opinion of some commentators does have its drawbacks. For instance, the flip-flopping of legislation back and forth as the majority in parliament changed between the Conservatives and Labour over the period 1940–1980, contesting over the nationalisation and privatisation of the British Steel Industry resulted in major instability for the British steel sector.<ref name = 0745-1253/>

=== [[Social:Political fragmentation|Political fragmentation]] ===
{{Undue weight|date=January 2024|to=by making broad generalisations but citing only one authority}}
In R. Kent Weaver's book ''Are Parliamentary Systems Better?'', he writes that an advantage of presidential systems is their ability to allow and accommodate more diverse viewpoints. He states that because "legislators are not compelled to vote against their constituents on matters of local concern, parties can serve as organizational and roll-call cuing vehicles without forcing out dissidents."<ref name = 0745-1253/>

=== Democratic unaccountability ===

All current parliamentary democracies see the indirect election or appointment of their head of government. As a result, the electorate has limited power to remove or install the person or party wielding the most power. Although strategic voting may enable the party of the prime minister to be removed or empowered, this can be at the expense of voters first preferences in the many parliamentary systems utilising first past the post, or having no effect in dislodging those parties who consistently form part of a coalition government, as with the current Dutch prime minister Mark Rutte and his party the [[Social:People's Party for Freedom and Democracy|VVD]]'s 4 terms in office, despite their peak support reaching only 26.6% in 2012.<ref>{{Cite news |last=Henley |first=Jon |date=14 December 2021 |title='Teflon' Mark Rutte set for fourth Dutch term after record-breaking talks |work=The Guardian |url=https://www.theguardian.com/world/2021/dec/14/teflon-mark-rutte-fourth-dutch-term-record-breaking-talks-government-coalition |url-access=registration |access-date=27 October 2022}}</ref>
