Polls open in triple by-election contest
The polls have opened in three by-elections where defeats would heighten Conservative fears that Rishi Sunak will struggle to lead them to another Commons majority.
The seats of Uxbridge and South Ruislip in west London, Selby and Ainsty in North Yorkshire, and Somerton and Frome in Somerset, are all up for grabs, with polls closing at 10pm.
Results are expected in the early hours of Friday.
The Prime Minister braced MPs at a meeting of the 1922 Committee of Tory backbenchers on the eve of the polls that they face a “tough battle”.
The three seats were left empty by outgoing Conservative MPs - former prime minister Boris Johnson and Nigel Adams - and former Tory David Warburton.
Constituents will need photo ID in order to vote.
