The 1950 United Kingdom general election was the first to be held after a full term of a majority Labour government. The general election was held on Thursday 23 February 1950, and was also the first to be held following the abolition of plural voting and university constituencies. The government's lead over the Conservative Party shrank dramatically, and Labour was returned to power but with an overall majority significantly reduced from 146 to just 5. There was a 2.8% national swing towards the Conservatives, who gained 90 seats. Labour called another general election the following year, which the Conservative Party won, returning Churchill to government after six years in opposition.

The Labour Party is a political party in the United Kingdom that has been described as an alliance of social democrats, democratic socialists, and trade unionists. The Labour Party sits on the centre-left of the political spectrum. In all general elections since 1922, Labour has been either the governing party or the Official Opposition. There have been six Labour prime ministers and thirteen Labour ministries. Since the 2010 general election, it has been the second-largest UK political party by the number of votes cast, behind the Conservative Party and ahead of the Liberal Democrats. The party holds the annual Labour Party Conference.
