MPs are set for a momentous third vote Friday on Prime Minister Theresa May's Brexit deal, which could end a months-long political crisis or risk Britain crashing out of the EU in two weeks.

The House of Commons has twice rejected May's withdrawal agreement, both times by large margins, but has been unable to agree any alternative -- and time is running out.
