The winners of Pakistan's parliamentary election will meet Sunday to finalize a power-sharing deal amid increasing pressure on the US-backed president to quit following the defeat of his political allies at the polls, a party spokesman said. Aides to former Prime Minister Nawaz Sharif and Asif Ali Zardari have been holding talks to discuss how to form a coalition government since the Feb. 18 elections when they routed the allies of President Pervez Musharraf. Zardari's party won the most votes, followed by Sharif's grouping. Zardari is the widow of slain opposition leader Benazir Bhutto. On Saturday, Sadiq ul-Farooq, a spokesman for Sharif's party, told The Associated Press that the leaders of two winning parties would meet Sunday. “Nawaz Sharif and Asif Ali Zardari will meet to give a final shape to matters about formation of the coalition government,” he said, adding “There is a progress in our talks.” Ul-Farooq provided no further details. Sharif - whose government was ousted by Musharraf in the 1999 coup - wants Musharraf to quit following the defeat. He also insists the former Chief Justice Iftikhar Mohammed Chaudhry and other judges sacked by Musharraf be reinstated. Zardari says such matters should be referred to the new parliament. __
