LONDON (Reuters) - Britain faces “total uncertainty” if lawmakers reject Prime Minister Theresa May’s Brexit deal on Tuesday, health minister Matt Hancock said on Sunday, adding that he did not think a defeat was inevitable.

“In the event of this vote on Tuesday not going through, nobody knows what would happen. In everything that followed there would be total uncertainty - that would be the only certainty,” Hancock told Sky News.
