2024 Wellingborough by-election

A by-election for the United Kingdom parliamentary constituency of Wellingborough was held on 15 February 2024, triggered by a recall petition that removed incumbent Conservative MP Peter Bone, following his suspension from the House of Commons for bullying and sexual harassment. The by-election was won by Gen Kitchen of the Labour Party.

Bone was suspended from the House of Commons for six weeks on 25 October 2023. The length of his suspension automatically initiated a recall petition which was held in late 2023. On 19 December, it was announced the petition had been successful and Bone was officially unseated under the terms of the Recall of MPs Act 2015.

The by-election resulted in the biggest swing from the Conservatives to Labour since the 1994 Dudley West by-election and the second biggest since the Second World War. It was also the largest ever drop in the Conservative Party vote share in a by-election, the largest drop in any party's vote share since the 1948 Glasgow Camlachie by-election, and the worst performance by the Conservatives in the constituency's history, falling below the 25.4% of the vote it received in 1923. The turnout was 38%, compared to a 64.3% turnout in the constituency at the last general election.

The by-election took place on the same day as the Kingswood by-election, also won by Labour from the Conservatives.
