LONDON (AP) — Former Treasury chief Rishi Sunak is set to become Britain’s next prime minister after winning the Conservative leadership race. He now faces the huge task of stabilizing the party and country at a time of economic and political turbulence. He will be Britain’s first leader of color, and the nation’s third leader just this year. Sunak will take over as prime minister from Liz Truss. She quit last week after 45 tumultuous days in office, leaving a staggering economy and a shell-shocked and divided party. His only rival conceded and withdrew after failing to reach the nomination threshold of 100 Conservative lawmakers needed to stay in the race.
