Theresa May’s government faces a vote of no confidence later after MPs rejected the PM’s Brexit deal.
The Commons defeat – by 432 votes to 202, the largest in history – came as a huge blow for Mrs May.
Labour launched the bid to trigger a general election after the deal setting out the terms of Britain’s exit from the EU was rejected by 230 votes, bbc.co.uk informs.
However, one senior party figure has suggested it is unlikely to succeed, with Northern Ireland’s DUP and Tory rebels saying they will back the PM.
The confidence vote is expected to be held on Wednesday.
PM Theresa May has told MPs she will return to the Commons with an alternative plan next week, provided she survives the confidence vote.
MPs are set to debate the motion for about six hours following Prime Minister’s Questions at 1200, with Labour leader Jeremy Corbyn saying it would allow them to give their verdict on “the sheer incompetence of this government”.
Despite the government’s heavy loss in the Brexit vote, Conservative rebels are likely to come back on-side in the confidence vote, the same source informs.
