2024 Wellingborough by-election

A by-election took place on Thursday 15 February 2024 in the UK Parliament constituency of Wellingborough. This followed a recall petition held in late 2023 that removed the incumbent MP Peter Bone under the terms of the Recall of MPs Act 2015, triggered by his six-week suspension from the House of Commons for bullying and sexual harassment.

The by-election was won by Gen Kitchen of the Labour Party. It was 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.
