Pakistan's two old-guard political parties agreed to form a government, a move that breaks an almost two-week deadlock and likely keeps jailed former premier Imran Khan's party out of power even though it won the most seats in the country's contentious election. Bilawal Bhutto Zardari's Pakistan Peoples Party will join a coalition with the Sharif clan's Pakistan Muslim League-Nawaz, Bhutto Zardari said at a joint news conference in the capital Islamabad close to midnight local time on Tuesday. Shehbaz Sharif will be prime minister while Bhutto Zardari's father, Asif Ali Zardari, will be nominated as president. "Both the parties have the numbers to form a government," Bhutto Zardari, 35, the son of slain former premier Benazir Bhutto, said, with his father and Sharif next to him.
