British Prime Minister Theresa May's
British Prime Minister Theresa May’s template to exit the European Union faces prospects of defeat as British lawmakers are set to vote on Brexit deal on coming Tuesday.

The U.K. Is set to leave the European Union at 11:00 p.m. London time on March 29, 2019.

The U.K. Government and EU heads of state have signed off on the preliminary deal and now U.K. Lawmakers have a meaningful vote to decide whether it can proceed.

May’s proposal is split into a withdrawal agreement, setting out the terms of the exit and a future relationship document.

Her proposal needs the backing of 320 lawmakers, more than half of the 639 members of parliament that vote in Westminster.

But, the numbers do not appear to be in May’s favor.

If the prime minister’s deal is voted down on Tuesday evening, the government would only have three parliamentary working days to come up with revised plans.

Theresa May’s resignation, a vote of no confidence in the government, a general election, a second referendum on EU membership, a temporary stop on Britain’s withdrawal, are a range of potential outcomes.
