Steven Tuckwell (born 1968 or 1969)[1] is a British politician who became the Member of Parliament (MP) for Uxbridge and South Ruislip from 2023 to 2024, in which he succeeded Boris Johnson, the former Prime Minister of the United Kingdom.

He lost his seat in the 2024 general election to Labour's Danny Beales, whom he had narrowly defeated in the 2023 by-election.

[1] Tuckwell won the seat of Uxbridge and South Ruislip in a by-election held on 20 July 2023 following the resignation of former prime minister Boris Johnson, who had represented the constituency for the Conservative Party since the 2015 general election.

[7] Tuckwell described the by-election as a "referendum on ULEZ", opposing the planned expansion of the Ultra Low Emission Zone (ULEZ) by Sadiq Khan, the Labour mayor of London,[3] and he ran a "one-issue campaign" that avoided mention of his own party.

[10] He was sworn in as an MP on 5 September 2023 following the summer break alongside Sarah Dyke and Keir Mather.
