Politics and government of
the United Kingdom
Brief history and overview 
Prior to the mid-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. In the late 19th century the Liberal Party began to pursue more left wing policies, and many of the heirs of the Whig tradition became Liberal Unionists and moved closer to the Conservatives on many of the key issues of the time.
The Liberal 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, who 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 since a third party (recently, the Liberal Democrats) can prevent 50% of the votes/seats from going to a single party. Following electoral co-operation as part of the SDP-Liberal Alliance, The Liberal Party merged with the Social Democratic Party in 1988 becoming the Liberal Democrats, which is now the largest third party.
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. Other than the Green Party of England and Wales, the only other parties winning seats in the House of Commons at the 2010 general election were based in Scotland, Wales and Northern Ireland.
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 per cent of the electorate) to 2005 (1.3 per cent).
Register of Political Parties 
The Electoral Commission's Register of Political Parties lists the details of parties registered to fight elections, and their registered name, in the United Kingdom. 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.
As of 10 June 2011[update] it shows the number of registered political parties as 419. In Northern Ireland there are 42 registered parties.
Major parties in the House of Commons 
Three parties dominate politics in the House of Commons. They all operate throughout Great Britain (only the Conservative and Unionist Party stands candidates in Northern Ireland). Most of the British Members of the European Parliament and the National Assembly for Wales represent one of these parties:
- Conservative and Unionist Party, centre-right (306 seats in the House of Commons)
- Labour Party, centre-left (a broad social-democratic party with Third Way policies, was traditionally democratic socialist in orientation) (258 seats)
- Co-operative Party (all Co-operative Party MPs are also Labour MPs as part of a long-standing electoral agreement)
- Liberal Democrats, radical-centrist (heavily influenced by social liberalism). (57 seats)
