Politics of the United Kingdom
The United Kingdom is a constitutional monarchy where executive power is delegated by legislation and social conventions to a unitary parliamentary democracy. From this a hereditary monarch, currently King Charles III, serves as head of state while the Prime Minister of the United Kingdom, currently Rishi Sunak since 2022, serves as the elected head of government.

The United Kingdom's parliamentary system sees executive power exercised by the British government, appointed on behalf of the monarch. This executive branch overlaps and is formed by members of the Parliament of the United Kingdom where legislative power is vested in the two parliamentary chambers of the House of Commons and the House of Lords. Asymmetrical powers are also granted to the devolved governments of Scotland, Wales and Northern Ireland within the Scottish Parliament, the Welsh Parliament, and the Northern Ireland Assembly.
The British political system is a multiple-party system[1] and was according to the V-Dem Democracy indices 2023 the 22nd most electorally democratic in the world.[2] Since the 1920s, the two dominant parties have been the Conservative Party and the Labour Party. Before the Labour Party rose in British politics, the Liberal Party was the other major political party, along with the Conservatives. While coalition and minority governments have been an occasional feature of parliamentary politics, the first-past-the-post electoral system used for general elections tends to maintain the dominance of these two parties, though each has in the past century relied upon a third party, such as the Liberal Democrats, to deliver a working majority in Parliament. A Conservative–Liberal Democrat coalition government held office from 2010 until 2015, the first coalition since 1945.[3] The coalition ended following parliamentary elections on 7 May 2015, in which the Conservative Party won an outright majority of seats, 330 of the 650 seats in the House of Commons, while their coalition partners lost all but eight seats.[4]
With the partition of Ireland, Northern Ireland received home rule in 1920, though civil unrest meant direct rule was restored in 1972. Support for nationalist parties in Scotland and Wales led to proposals for devolution in the 1970s, though only in the 1990s did devolution happen. Today, Scotland, Wales and Northern Ireland each possess a legislature and executive, with devolution in Northern Ireland being conditional on participation in certain all-Ireland institutions. The British government remains responsible for non-devolved matters and, in the case of Northern Ireland, co-operates with the government of the Republic of Ireland. Devolution of executive and legislative powers may have contributed to increased support for independence in the constituent parts of the United Kingdom.[5] The principal Scottish pro-independence party, the Scottish National Party, became a minority government in 2007 and then went on to win an overall majority of MSPs at the 2011 Scottish parliament elections which formed the current Scottish Government administration. In a 2014 referendum on independence 44.7% of voters voted for independence versus 55.3% against.[6] In Northern Ireland, Irish nationalist parties such as Sinn Féin advocate Irish reunification. In Wales, Welsh nationalist parties such as Plaid Cymru support Welsh independence.
The constitution of the United Kingdom is uncodified, being made up of constitutional conventions, statutes and other elements. This system of government, known as the Westminster system, has been adopted by other countries, especially those that were formerly parts of the British Empire. The United Kingdom is also responsible for several dependencies, which fall into two categories: the Crown Dependencies, in the immediate vicinity of the UK, are strictly-speaking subject to the Crown (i.e., the Monarch) but not part of the sovereign territory of the United Kingdom (though de facto British territory), and British Overseas Territories, as British colonies were re-designated in 1983, which are part of the sovereign territory of the United Kingdom, in most of which aspects of internal governance have been delegated to local governments, with each territory having its own first minister, though the title used may differ, such as in the case of the Chief Minister of Gibraltar, though they remain subject to the Parliament of the United Kingdom (when United Kingdom is used to refer only to that part of the British Realm, or sovereign British territory, which is governed directly by the British Government, and not via local subsidiary governments, United Kingdom logically refers to a local government area, though the national government performs the role of local government within that area).
The British monarch, currently King Charles III, is the head of state of the United Kingdom. Though he takes little direct part in government, the Crown remains the fount in which ultimate executive power over government lies. These powers are known as royal prerogative and can be used for a vast amount of things, such as the issue or withdrawal of passports, to the dismissal of the prime minister or even the declaration of war. The powers are delegated from the monarch personally, in the name of the Crown, and can be handed to various ministers, or other officers of the Crown, and can purposely bypass the consent of Parliament.
The head of His Majesty's Government, the prime minister, also has weekly meetings with the sovereign, where they may express their feelings, warn, or advise the prime minister in the government's work.[7]
According to the uncodified constitution of the United Kingdom, the monarch has the following powers:[8]
Domestic powers
Foreign powers
Various electoral systems are used in the UK:
The use of the first-past-the-post to elect members of Parliament is unusual among European nations. The use of the system means that when three or more candidates receive a significant share of the vote, MPs are often elected from individual constituencies with a plurality (receiving more votes than any other candidate), but not an absolute majority (50 percent plus one vote).
Elections and political parties in the United Kingdom are affected by Duverger's law, the political science principle that states that plurality voting systems, such as first-past-the-post, tend to lead to the development of two-party systems. The UK, like several other states, has sometimes been called a "two-and-a-half party system" because parliamentary politics is dominated by the Labour Party and Conservative Party, while the Liberal Democrats used to hold a significant number of seats (but still substantially less than Labour and the Conservatives), and several small parties (some of them regional or nationalist) trailed far behind in the number of seats, although this changed in the 2015 general election.
In the last few general elections, voter mandates for Westminster in the 30–40% ranges have been swung into 60% parliamentary majorities. No single party has won a majority of the popular vote since the Third National Government of Stanley Baldwin in 1935. On two occasions since World War II – 1951 and February 1974 – a party that came in second in the popular vote came out with the largest number of seats.
Electoral reform for parliamentary elections has been proposed many times. The Jenkins Commission report in October 1998 suggested implementing the Alternative Vote Top-up (also called alternative vote plus or AV+) in parliamentary elections. Under this proposal, most MPs would be directly elected from constituencies by the alternative vote, with a number of additional members elected from "top-up lists." However, no action was taken by the Labour government at the time. There are several groups in the UK campaigning for electoral reform, including the Electoral Reform Society, Make Votes Count Coalition, and Fairshare. The boundary commission for England has also suggested in its 2023 boundary review that constituency lines should be redrawn to allow constituencies to have a similar number of residents.
The 2010 general election resulted in a hung parliament (no single party was able to command a majority in the House of Commons). This was only the second general election since World War II to return a hung parliament, the first being the February 1974 election. The Conservatives gained the most seats (ending 13 years of Labour government) and the largest percentage of the popular vote but fell 20 seats short of a majority.
The Conservatives and Liberal Democrats entered into a new coalition government, headed by David Cameron. Under the terms of the coalition agreement, the government committed itself to holding a referendum in May 2011 on whether to change parliamentary elections from first-past-the-post to AV. Electoral reform was a major priority for the Liberal Democrats, who favour proportional representation but were able to negotiate only a referendum on AV (the alternative vote system is not a form of proportional representation) with the Conservatives. The coalition partners campaigned on opposite sides, with the Liberal Democrats supporting AV and the Conservatives opposing it. The referendum resulted in the Conservatives' favour, and the first-past-the-post system was maintained.
