2024 Wellingborough by-election
|15 February 2024
Labour's Gen Kitchen won the by-election with 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%.
