UK MPs to vote on Brexit

UK MPs will vote again later on Brexit - and Prime Minister Theresa May's facing another possible defeat. 

Some lawmakers in her own party are considering not backing the government in a vote on whether they support her Brexit approach.

It's not the final vote on Theresa May's Brexit deal, to which she is still trying to negotiate changes with the European Union.

But Correspondent Olly Barratt says Thursday's vote is still potentially important.
