LONDON: British lawmakers defeated Prime Minister Theresa May’s Brexit divorce deal by a crushing margin on Tuesday, triggering political upheaval that could lead to a disorderly exit from the EU or even to a reversal of the 2016 decision to leave.

Parliament voted 432-202 against her deal, the worst parliamentary defeat for a government in recent British history. Scores of her own lawmakers – both Brexiteers and supporters of EU membership – joined forces to vote down the deal.
