Boris Johnson faced furious recriminations over his failure to sack Matt Hancock last night after the Tories were narrowly deprived of victory in the Batley and Spen by-election.
Labour overcame the odds to hold the seat by just 323 votes, providing a desperately needed boost for Sir Keir Starmer's leadership.
The disappointing result for the Conservatives prompted an immediate blame game, with the party's chairman pointing the finger at the former health secretary's affair.
Amanda Milling admitted that Mr Hancock's breaking of coronavirus rules by kissing a married aide 'was something that came up on the doorstep'.
But angry backbenchers claimed the party could actually have taken the seat if the Prime Minister had sacked the minister when the news first broke.
