The Latest on Britain’s exit from the European Union:

British lawmakers have rejected Prime Minister Theresa May’s Brexit deal by a huge margin, plunging U.K. politics into crisis 10 weeks before the country is due to leave the European Union.

The House of Commons voted 432 -202 on Tuesday against the deal struck between Britain’s government and the EU in November.

Legislators from both pro-EU and pro-Brexit sides of Britain’s political divide rejected May’s entreaties to back the deal and deliver on citizens’ the June 2016 vote to leave the 28-nation bloc.

The defeat leaves May’s leadership wobbling and the government with just a few days, until Monday, to come up with a “Plan B.”

Unless a deal is ratified, Britain is set for a disorderly exit from the bloc on March 29, with potentially tumultuous economic and social consequences.
