Steven Tuckwell (born 1968 or 1969)^[1] is a British politician who has served as the Member of Parliament (MP) for Uxbridge and South Ruislip in Greater London since the 2023 by-election, in which he succeeded Boris Johnson, the former Prime Minister of the United Kingdom. A member of the Conservative Party, he has also sat on Hillingdon Borough Council since 2018.

Steven Tuckwell^[2] was born in Hillingdon Hospital. His family have lived in Hillingdon for three generations. He attended local schools including Bishop Ramsey School in Ruislip.^[3][4]

Tuckwell previously worked as a manager for Royal Mail.^[3] In the May 2018 election, he was elected a Conservative councillor for the ward of South Ruislip on Hillingdon London Borough Council.^[5][3][6] At the time of his election to parliament, he worked for a vehicle leasing company.^[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.^[8] Danny Beales, the Labour by-election candidate, also criticised the expansion.^[9] Labour leader Keir Starmer blamed the policy for the party's failure to take the seat.^[10]

He was sworn in as an MP on 5 September 2023 following the summer break alongside Sarah Dyke and Keir Mather.^[11] Dyke, a Liberal Democrat, was elected to serve Somerton and Frome, and Mather, from the Labour Party, was elected for Selby and Ainsty in two by-elections held the same day as Tuckwell's.

Tuckwell lives in Hillingdon with his partner, Rachel. His two children attended local schools.^[3][5]
