LONDON — At least 150 Conservative Party lawmakers have indicated support for Prime Minister Theresa May ahead of a confidence vote in her leadership later on Wednesday, based on public statements in the media and social media. May needs to secure a simple majority -- 158 of 315 lawmakers -- to remain leader. A secret ballot will be held between 1800 and 2000 GMT. However, British political commentators report some lawmakers who back May in public say privately they will vote against her.
