The February 1974 United Kingdom general election was held on Thursday 28 February 1974. The Labour Party, led by Leader of the Opposition and former Prime Minister Harold Wilson, gained 14 seats but was seventeen short of an overall majority. The Conservative Party, led by incumbent Prime Minister Edward Heath, lost 28 seats. That resulted in a hung parliament, the first since 1929. Heath sought a coalition with the Liberals, but the two parties failed to come to an agreement and so Wilson became Prime Minister for a second time, his first with a minority government. Wilson called another early election in September, which was held in October and resulted in a Labour majority. The February election was also the first general election to be held with the United Kingdom as a member state of the European Communities (EC), which was widely known as the "Common Market".

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.
