British Prime Minister Theresa May won a two-week reprieve on Wednesday from British lawmakers, who postponed a threatened rebellion aimed at blocking a no-deal Brexit after she agreed to a possible delay to Britain's departure from the EU.

But the opposition Labour Party announced it would now support a new public vote on Brexit, the first time since Britain voted in 2016 to leave the EU that one of its main parties has backed giving voters a chance to change their minds.

After months of saying that Britain must leave the EU on time on March 29, May opened up the possibility on Tuesday of a short limited extension to the exit date.
