Ugandan President Yoweri Museveni looked certain to extend his two-decade rule as 80 percent of official election results on Saturday gave him an almost unassailable lead over his main rival Kizza Besigye. Electoral Commission figures released at 10.30 a.m. (0730 GMT) gave Museveni 60.6 percent and Besigye 36.0 percent of votes from Thursday's election, the east African nation's first multi-party polls in a quarter of a decade, according to a report of Reuters.
