This article lists political parties in the United Kingdom.

Brief history and overview
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 Right supported a smaller state with less influence on the lives of the public, and the Left advocated the opposite. 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 quite 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 in terms of votes.

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  when UKIP and the Green Party of England and Wales received 4.9 million votes (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, and the Green Party of England and Wales, together with its Scottish and Northern Ireland affiliated parties, the Scottish National Party and Plaid Cymru, delivered a petition signed by 477,000 people to Downing Street demanding electoral reform.

Since 1997, proportional representation-based voting systems have been adopted for elections to the Scottish Parliament, the National Assembly for Wales, the Northern Ireland Assembly, the London Assembly and 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, falling by over 65% from 1983 (4% of the electorate) to 2005 (1.3%).

The start of political parties
The Electoral Commission's Register of Political Parties lists the details of parties registered to fight elections in the United Kingdom, including their registered name. Under current electoral law, including the Registration of Political Parties Act, 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.

the Electoral Commission showed the number of registered political parties in Great Britain and Northern Ireland as 492.

Parliamentary parties
Two parties dominate politics in the House of Commons. Each one operates throughout Great Britain (only the Conservative and Unionist Party stands candidates in Northern Ireland). Most of the British Members of the European Parliament, Scottish Parliament and the National Assembly for Wales represent one of these parties:


 * Conservative and Unionist Party, centre-right (314 seats in the House of Commons)
 * Labour Party, centre-left (246 seats)
 * Co-operative Party (all Co-operative Party MPs are also Labour MPs as part of a long-standing electoral agreement)
