An extraordinary 118 Tory rebels, more than a third of the parliamentary party, joined forces with Labour to sink Mrs May’s withdrawal agreement by 432 votes to 202 – a majority of 230 – on a dramatic day at Westminster.
Moments after the result was announced Jeremy Corbyn announced he would table a no-confidence motion, which MPs will vote on tonight, in a bid to force a general election.
But the PM’s Northern Irish allies, former Foreign Secretary Boris Johnson, and backbench ringleader Jacob Rees-Mogg have all pledged to support her, meaning she is likely to survive.
The DUP’s Sammy Wilson said the party wanted to ‘get the government back on track’ and would back Mrs May, while Mr Rees-Mogg said last night: ‘I will be supporting the Prime Minister’.
Mr Johnson said he ‘certainly shall’ vote for the PM in Wednesday night’s vote, saying he did not want Mr Corbyn in office instead.
