Lawyers for Ugandan opposition leader Bobi Wine filed a challenge in the Supreme Court on Monday against President Yoweri Museveni's victory in last month's election, claiming the poll was rigged. "We want nullification of the election. We do not want (Museveni) participating in any future election," said Medard Sseggona, one of Wine's lawyers, at the Kampala courthouse where he filed the petition for the runner-up in the January 14 presidential election. moh-np/fb/ri
