LONDON (Reuters) - British Prime Minister Theresa May’s lawmakers could vote on a no confidence motion in her leadership as soon as Wednesday night, said a Conservative lawmaker who has long been critical of May.

“We will have a confidence motion so Conservative MPs (members of parliament) will vote whether they have confidence or not in a secret ballot at the first opportunity which I think could be tomorrow night,” Andrew Bridgen told Sky News.
