Theresa May’s government faces a vote of no confidence later after MPs rejected the PM’s Brexit deal.
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.
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 at about 19:00 GMT.
Mrs May has told MPs she will return to the Commons with an alternative plan next week, provided she survives the confidence vote.
“The House has spoken and this government will listen,” she said on Tuesday night, offering cross-party talks to determine a way forward.
