Prime Minister Theresa May was trying to forge consensus in Parliament on a Brexit divorce agreement on Wednesday after the crushing defeat of her own deal left Britain's exit from the European Union in disarray 10 weeks before it is due to leave.
May was widely expected to see off an attempt by the opposition Labour Party to bring down her government, having secured the backing of her own party's rebels and the small Northern Irish party, which props up her minority administration.
The confidence motion, called on Tuesday after lawmakers rejected May's Brexit deal by 432-202 — the worst defeat for a British government in modern times — will be held at 1900 GMT.
