Swansea East by-election, 1940

The Swansea East by-election, 1940 was a parliamentary by-election held for the British House of Commons constituency of Swansea East on 8 May 1933. The seat had become vacant on the resignation from the House of Commons of the Labour Member of Parliament David Williams, who had held the seat since the 1922 general election.

During World War II, the major parties had agreed not to contest by-elections when vacancies arose in seats held by the other parties, so the Labour candidate, David Mort, was returned unopposed. He represented the constituency until his death in 1963, triggering another by-election.
