LONDON, Broadcasting News Corporation : Prime Minister Boris Johnson of Britain was battling for his political survival after two senior ministers in his Conservative government unexpectedly resigned from their cabinet posts in what appeared to be a coordinated move against their leader. Rishi Sunak, the chancellor of the Exchequer, and Sajid Javid, the health secretary, announced their decisions shortly after Johnson apologized for having appointed a minister, Chris Pincher, who stepped down last week over accusations of inappropriate behavior. The resignations thrust Johnson into the most perilous position of his three-year tenure as prime minister. He survived a no-confidence vote last month, but cabinet resignations could put pressure on him to resign. News collected from The New York Times.
