List of United Kingdom by-elections (1950–1979)

This is a list of parliamentary by-elections in the United Kingdom, 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, green for a Plaid Cymru gain and grey for any other gain.

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.

^ ^a ^b ^c Gain not retained at the 1959 UK general election. ^ ^a ^b Gain retained at the 1959 UK general election. ^ ^a ^b Tom Mitchell won the most votes in the 1955 General Election but was disqualified by the House of Commons on the grounds that he was a convicted felon. A by-election was called at which Mitchell again stood and won the most votes. On this occasion an election petition was lodged and Mitchell was again disqualified with the Election Court declaring his opponent Charles Beattie duly elected. It was then discovered that Beattie was ineligible to sit because he held offices of profit under the Crown. Beattie was indemnified by Parliament against the consequences of sitting and voting while ineligible, and a further writ was moved. In the subsequent by-election Independent Unionist George Forrest gained more votes than Mitchell and duly took his seat. Subsequently Forrest took the Ulster Unionist whip and won the seat in his new party colours at the 1959 General Election. 40th Parliament (1951–1955)

It was then discovered that Beattie was ineligible to sit because he held offices of profit under the Crown. Beattie was indemnified by Parliament against the consequences of sitting and voting while ineligible, and a further writ was moved. In the subsequent by-election Independent Unionist George Forrest gained more votes than Mitchell and duly took his seat. Subsequently Forrest took the Ulster Unionist whip and won the seat in his new party colours at the 1959 General Election.
