U.K. lawmakers are set to vote on Prime Minister Theresa May's Brexit plan on Tuesday... and it's expected to fail.
The British government and EU heads of state have already rubber-stamped a preliminary Brexit deal, but the U.K. Parliament still has to give its approval. May will need support from more than half of the 639 members of Parliament who vote to move the plan forward.
If May's Brexit deal is shot down by Parliament, her government will only have three parliamentary working days to come up with a back up plan. The deadline for the U.K.'s exit from the EU is coming up quick — March 29.
And if no plan is approved before the impending deadline? There are a few probable options, including a disorderly "no-deal" exit from the EU, the British government possibly collapsing or lawmakers blocking Brexit entirely.
