List of political parties in the United Kingdom

The Electoral Commission's Register of Political Parties^[1] lists the details of political parties registered to contest elections in the United Kingdom, including their registered name. Under current electoral law, including the Registration of Political Parties Act 1998, the Electoral Administration Act 2006, and the Political Parties, Elections and Referendums Act 2000, only registered party names can be used on ballot papers by those wishing to fight elections. Candidates who do not belong to a registered party can use "independent" or no label at all. As of 25 May 2024^[update], the Electoral Commission showed the number of registered political parties in Great Britain and Northern Ireland as 393.^[2]

Before the middle of the 19th century, politics in the United Kingdom was dominated by the Whigs and the Tories. These were not political parties in the modern sense but somewhat loose alliances of interests and individuals. The Whigs included many of the leading aristocratic dynasties committed to the Protestant succession, and later drew support from elements of the emerging industrial interests and wealthy merchants, while the Tories were associated with the landed gentry, the Church of England and the Church of Scotland.

By the mid 19th century, the Tories had evolved into the Conservative Party, and the Whigs had evolved into the Liberal Party. The concept of right and left came originally from France, where the supporters of a monarchy (constitutional or absolute) sat on the right wing of the National Assembly, and republicans on the left. In the late 19th century, the Liberal Party began to lean towards the left. Liberal Unionists split off from the Liberals over Irish Home Rule and moved closer to the Conservatives over time.

The Liberals and Conservatives dominated the political scene until the 1920s, when the Liberal Party declined in popularity and suffered a long stream of resignations. It was replaced as the main anti-Tory opposition party by the newly emerging Labour Party, which represented an alliance between the labour movement, organised trades unions and various socialist societies.

Since then, the Conservative and Labour parties have dominated British politics, and have alternated in government ever since. However, the UK is not a two-party system as other parties have significant support. The Liberal Democrats were the third largest party until the 2015 general election when they were overtaken by the Scottish National Party in terms of seats and UK political party membership, and by the UK Independence Party (UKIP) in terms of votes. The Liberal Democrats regained the status of the third largest political party in the UK by seats with the outcome of the 2024 United Kingdom general election, although in the 2025 United Kingdom local elections Reform beat the Lib Dems both in vote share and in number of councils gained.

House of Lords chamber

The UK's first-past-the-post electoral system leaves small parties disadvantaged on a UK-wide scale. It can, however, allow parties with concentrations of supporters in the constituent countries to flourish. In the 2015 election, there was widespread controversy^[3][4][5] when the UK Independence Party (UKIP) and the Green Party of England and Wales received 4.9 million votes^[6] (12.6% of the total vote for UKIP and 3.8% for the Greens) yet only gained one seat each in the House of Commons. After that election, UKIP, the Liberal Democrats, the Scottish National Party, Plaid Cymru, and the Green Party of England and Wales, together with its Scottish and Northern Ireland affiliated parties, delivered a petition signed by 477,000^[7] people to Downing Street demanding electoral reform.

Since 1997, proportional representation-based voting systems have been adopted for elections to the Scottish Parliament, the Senedd (Welsh Parliament), the Northern Ireland Assembly, the London Assembly and (until Brexit in 2020) the UK's seats in the European Parliament. In these bodies, other parties have had success.

Traditionally political parties have been private organisations with no official recognition by the state. The Registration of Political Parties Act 1998 changed that by creating a register of parties.

Membership of political parties has been in decline in the UK since the 1950s. Membership has fallen by over 65% since 1983, from 4% of the electorate to 1.3% in 2005.^[8]

Party descriptions

Party		Description
	Labour Party	A social democratic party that has its roots in the trade union movement. The party has several internal factions, which include: Progressive Britain, which promotes a continuation of New Labour policies and is considered to be on the right of the party; the soft-left Open Labour; Momentum, which represents the party's left-wing, democratic socialist grouping; and Blue Labour, which promotes socially and culturally conservative values while remaining committed to labour rights and left-wing economics. Labour also has candidates who stand on a split-ticket with the Co-operative Party.
	Co-operative Party	A party that promotes cooperative principles and values, providing political representation for the British co-operative movement. Since 1927, the party has been in an electoral alliance with the Labour Party, standing joint candidates under the Labour and Co-operative label.
	Conservative and Unionist Party	A politically conservative party loosely divided into three categories: the One Nation Conservatives, the Thatcherites, who strongly support a free market with restrained government spending and tend to be Eurosceptic; and the Cornerstone Group.
	Liberal Democrats	A liberal party; its main branches are social liberals based around the Social Liberal Forum, and the more centrist Liberal Reform grouping, which places more of an emphasis on economic liberalism. There is also a social democratic faction and influence within the party.
	Scottish National Party (SNP)	Scottish nationalist and social democratic party which supports Scottish independence and membership of the European Union or further devolution for Scotland.
	Sinn Féin	Irish republican party dedicated to the reunification of Ireland and the creation of a new republic based on democratic socialist values. It holds a policy of abstentionism for the House of Commons, with its MPs not taking their seats in this legislature.

	Democratic Unionist Party (DUP)	Strongly British unionist party in Northern Ireland which promotes social and national conservatism.
	Green Party of England and Wales	Green party that combines environmentalism and sustainability with left-leaning economic policies, while taking a progressive approach socially. The party also has eco-socialist and anti-capitalist factions, such as the Green Left grouping.
	Plaid Cymru	Centre-left, social democratic, and Welsh nationalist party in favour of Welsh independence or further devolution of powers to Wales while Wales remains part of the UK.
	Social Democratic and Labour Party (SDLP)	Irish nationalist and social-democratic party supporting a united Ireland.

	Traditional Unionist Voice (TUV)	Strongly social and national conservative unionist party in Northern Ireland. It has formed an alliance with Reform UK.
	Scottish Greens	Green party in favour of Scottish independence and Scottish republicanism.
	Alba Party	Formed as a breakaway party from the SNP, the party promotes Scottish independence, Scottish nationalism and Scottish republicanism, while taking a more socially conservative stance than the SNP.

This is a table of notable minor parties. Many parties are registered with the Electoral Commission but do not qualify for this list as they have not received significant independent coverage.
