List of United Kingdom by-elections (1931–50)

This is a list of parliamentary by-elections in the United Kingdom held between 1931 and 1950, with the names of the incumbent and victor and their respective parties. Where seats changed political party at the election, the result is highlighted: red for a Labour gain, blue for a Conservative gain, orange for a Liberal gain, yellow for a SNP gain and grey for any other gain.


Where the cause of by-election is given as "resignation" or "seeks re-election", this indicates that the incumbent was appointed on his or her own request to an "office of profit under the Crown", either the Steward of the Chiltern Hundreds or the Steward of the Manor of Northstead. These appointments are made as a constitutional device for leaving the House of Commons, whose Members are not permitted to resign.

  3. Down was a two member constituency. Little was elected as an official Ulster Unionist in the 1939 Down by-election. Prior to the 1945 general election he resigned from the party in protest at being subject to a reselection due to the retirement of Viscount Castlereagh, the other official Unionist MP, and held his seat as an Independent Ulster Unionist. Multi-member constituencies were abolished at the 1950 general election, but the Ulster Unionists won both successor seats, North Down and South Down.
  4. The last uncontested by-election on the British mainland to date.
  5. 1 2 Both Pym and Campbell died after the close of polling, but before the declaration. They were returned at the head of the poll in their respective constituencies, and declared elected posthumously.
  6. Dobbs was killed in a road accident the day after his election, making him the shortest-serving MP in British history.

37th Parliament (1935–1945)

This Parliament's life was extended by annual Prolongation of Parliament Acts for the duration of the Second World War. By-elections continued to fill vacancies. An electoral truce was negotiated between the Conservative, Labour, Liberal, National Liberal and National Labour parties, and National independent MPs that they would not contest by-elections which another party held (although there were a few occasions when a National party would step aside from a vacancy in favour of a National independent, usually a government minister). However many independents stood, including some party members who disagreed with the truce. The Common Wealth Party was formed in part with a view to contesting wartime by-elections.

In the 1935 general election it elected two Conservative and one National Liberal MPs. One Conservative (Noel Skelton) died between polling and the declaration of the results and the resulting by-election was won by Ramsay MacDonald for National Labour. He died within two years and the resultant by-election was won by Sir John Anderson as a non-party supporter of the National Government. In 1945 the National Liberal member (George Alexander Morrison) resigned and the resulting by-election was won by John Boyd-Orr as an Independent. Both Anderson and Boyd-Orr held their seats at the 1945 general election along with one Conservative.
  6. Prior to the by-election White was the Labour prospective parliamentary candidate for the constituency but resigned in order to contest the seat in defiance of the truce between the parties. In Parliament he took the Labour whip and retained the seat in the 1945 general election as an official Labour candidate.
  7. Loverseed gained Eddisbury for Common Wealth from the Conservatives in 1943, but subsequently sat as an independent Labour member then took the Labour Party whip. He defended the seat in the 1945 general election for Labour but lost to the National Liberals.

  12. 1 2 Southampton was a two-member constituency. In the 1935 general election it elected one National Liberal and one non-party supporter of the National Government. In February 1940 Sir John Reith (the newly appointed Minister of Information) was elected unopposed to fill a National Liberal vacancy as a non-party supporter of the National Government. In November 1940 he was elevated to the peerage and in the resulting unopposed by-election his seat was regained by the National Liberals. In the 1945 general election both seats were won by the Labour Party.

  14. Cambridge University was a two-member constituency. In the 1935 general election it elected two Conservative MPs. Hill took one seat from the Conservatives as an Independent Conservative, but did not contest 1945 general election, in which the two seats were won by one Conservative and one Independent.
  15. 1 2 The City of London was a two member constituency. In the 1935 general election it elected two Conservative MPs. In February 1940 Sir Andrew Duncan (the newly appointed President of the Board of Trade) was elected unopposed to fill one vacancy as a non-party supporter of the National Government. In the 1945 general election Duncan and a Conservative won the City's two seats.
  16. The Duchess of Atholl had resigned the National Government whip over foreign policy and in November 1938 was deselected as a candidate by her local association. She decided to resign her seat and fight a by-election as an Independent in opposition to the policy of appeasement. She lost the seat to the new Conservative candidate.
  17. In 1942 Bartlett co-founded the Common Wealth Party and served on its National Committee, but resigned two months later and reverted to being an Independent Progressive MP, retaining the seat in his original colours in the 1945 general election.
  18. The Dartford county constituency was divided in a mini redistribution in 1945 into two borough constituencies - Bexley and Dartford. Labour upheld its by-election gain in both constituencies with Adamson carrying the Bexley seat.
  19. Lipson was elected as an Independent Conservative but in Parliament supported the National Government. He was re-elected in the 1945 general election as an independent supporter of Churchill's government.
