List of MPs elected in the 1945 United Kingdom general election

This diagram show the composition of the parties in the 1945 general election.

Note: This is not the official seating plan of the House of Commons, which has five rows of benches on each side, with the government party to the right of the speaker and opposition parties to the left, but with room for only around two-thirds of MPs to sit at any one time. The Commons Chamber was hit by bombs and the roof of Westminster Hall was set on fire. The fire service said that it would be impossible to save both, so it was decided to concentrate on saving the Hall. The Commons Chamber was entirely destroyed by the fire which spread to the Members' Lobby and caused the ceiling to collapse. By the following morning, all that was left of the Chamber was a smoking shell. As the Commons Chamber was totally destroyed and the Lords Chamber was damaged, both Houses moved to the Church House annexe and sat there from 13 May. From late June 1941 until October 1950, the Commons met in the Lords Chamber, while the Lords met in the Robing Room (a fact which was kept secret during the war).[1]

° Sir Edward Campbell died on 17 July and Leslie Pym died on 18 July before the poll was announced. By-elections were held in the autumn
× The sitting MP for Hull, Central, Walter Windsor, died during the election campaign. Mark Hewitson was elected in a postponed poll in August.
