British Prime Minister Theresa May is to face a vote of no confidence Wednesday. Voting among Conservative members of British Parliament will take place over two hours starting at 6 p.m. GMT (1 p.m. EST).
May will need the votes of 158 MPs to retain leadership of the party and the Prime Ministership.
At least 15% of the parliamentary Conservative party, or 48 MPs, signed letters to the 1922 Committee of Tory backbenchers to trigger to the vote.
The vote comes after May postponed a parliamentary vote on her Brexit deal in the face of its certain defeat.
