The 1951 United Kingdom general election was held on Thursday, 25 October 1951, just twenty months after the previous general election in 1950; the Labour government called the election in hopes of increasing its parliamentary majority. However, this backfired, as even though Labour won the most votes, it was the Conservatives who won a majority, with the collapse of the Liberal vote allowing the Conservatives to gain seats by default.
Up to that point, the Labour Party achieved the most votes cast for a party; however, this would be surpassed several times, with the Conservatives breaking the record in 1992 and 2019. (13,948,385 is also the highest number of votes Labour ever won in a general election.) The Conservatives would also exceed the popular vote percentage (48.8%) achieved by Labour, in 1955 and 1959, winning over 49% in both cases. Turnout in this election declined slightly.
