MP before election Boris Johnson Conservative Elected MP Steve Tuckwell Conservative

A by-election for the United Kingdom parliamentary constituency of Uxbridge and South Ruislip was held on 20 July 2023, following the resignation of former Prime Minister Boris Johnson as its member of Parliament (MP) on 12 June.

The Conservative Party's candidate, Steve Tuckwell, held the seat with a reduced majority of 495 votes. The result was considered an upset, as Labour had targeted the seat heavily; a large backlash against Johnson was expected in the constituency in the wake of the Partygate affair. Tuckwell attributed his victory to the unpopularity of London's Ultra Low Emission Zone scheme and its proposed expansion into the Borough of Hillingdon.^[1]
