List of United Kingdom by-elections (1918–1931)

This is a list of parliamentary by-elections in the United Kingdom held between 1918 and 1931, 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, and grey for any other gain. A total of 233 by-elections were held during this period.

Resignations

See Resignation from the British House of Commons for more details.

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.

An uncontested by-election. The Guildford by-election was initially contested but on 25 August the Liberal candidate withdrew, in light of the changed political situation due to the formation of the National Government the previous day. Retained at the 1931 general election. Sunderland was a two member constituency. Both MPs were won by Labour in the 1929 general election and by the Conservatives in the 1931 general election. Taylor joined the Conservative Party in 1931, holding the seat at the 1931 general election. A rare case of a gain in an unopposed election. O'Connor had an ad hoc group of supporters in the constituency who helped his campaign at election times, and Logan had been extensively involved in the Irish nationalist movement in his youth. Preston was a two member constituency. Jowitt was appointed Attorney General of England and Wales in the Labour government and opted to seek re-election in his new party colours. In 1931 he became a National Labour MP but did not recontest Preston in the 1931 general election as he could not secure the withdrawal of Conservative candidates supporting the National Government who took both seats. 34th Parliament (1924–1929)

Gain retained at the 1923 general election. Gain not retained at the 1923 general election. 31st Parliament (1919–1922) Some precise party allegiances are difficult to determine as during this Parliament the Liberal and Conservative Parties were both divided over whether or not to continue support for the Lloyd George Coalition Government. Some opponents of the Coalition ran and/or sat as Independent Liberals or Conservatives respectively; however other opponents were able to secure official nominations. It is not always clear just where an individual MP or officially endorsed candidate stood on the Coalition at the point of election and there are several who appear to have given ambiguous information at the time or to have switched wings once in Parliament.
