LONDON: Efforts to unseat British Prime Minister Keir Starmer are likely to break out into open rebellion Thursday, with one potential rival expected to announce his bid for the job and another clearing the way for her to enter any future leadership contest. Allies of Health Secretary Wes Streeting say he will make an announcement later in the day after garnering enough support from lawmakers of the governing Labour Party to challenge Starmer for leadership of the party and the government.
