Ugandan opposition leader Bobi Wine filed a challenge Monday in the country’s Supreme Court seeking the cancellation of presidential election results declaring incumbent President Yoweri Museveni the winner.

Wine, whose real name is Robert Kyagulani, asked the International Criminal Court last month to investigate Museveni, Security Minister Elly Tumwine and eight other senior officials for sanctioning human rights abuses.

Wine ran against Museveni in the January 14 presidential election. Museveni, who has served as president since 1986, was declared the winner of the 2021 presidential election with 59 percent of votes, while Wine had 35 percent. Wine was placed on house arrest following the election. On January 25, a Ugandan court ordered security forces to stop surrounding his home and blocking him from leaving.

Wine has asked the court to overturn the results on several grounds, including the widespread use of violence.

There have been challenges to the past four elections that Museveni won, all of which were dismissed by the Supreme Court.
