Live updates: Rishi Sunak to become U.K. prime minister after Penny Mordaunt withdraws from leadership contest

LONDON — Rishi Sunak will be Britain’s next prime minister, the first person of color in the job, after dark-horse challenger Penny Mordaunt withdrew from the Conservative Party’s leadership contest. Sunak, 42, will be Britain’s third leader in less than two months. Sunak, the former finance minister who led the revolt against Boris Johnson and was runner-up to Liz Truss in September, will succeed them both, with the challenges of improving Britain’s economic trajectory and public trust in the Conservative Party.
