A general election was held on 12 December 2019 to elect all 650 members to the House of Commons of the United Kingdom. The Conservative Party won with a landslide majority and Boris Johnson stayed as Prime Minister. The Labour Party lost 60 seats, giving them their lowest number of seats (202) since 1935.

Labour leader Jeremy Corbyn quit after the loss saying he "would not lead Labour at the next election". This led to a leadership election in the party where Keir Starmer became the new leader.
