U.K. Boris Johnson on Thursday said he would step down in a defiant address in which he talked of his administration’s achievements and noted his standings in the polls despite a difficult economic backdrop. “When the herd moves, it moves,” said Johnson of his fellow Conservative parliamentary members. He thanked voters for an “incredible mandate” but said a “Darwinian” system would produce a new leader. He said he will stay on as caretaker leader until a replacement is found.
