Veteran Ugandan opposition politician Kizza Besigye has been charged with treason in a civilian court after his controversial case was transferred from a military tribunal. Treason is a capital offence in Uganda and if found guilty the 68-year-old cold be sentenced to death.

A Ugandan court charged opposition leader Kizza Besigye with treason over an alleged plot to end President Yoweri Museveni’s four-decade rule of the East African nation.

Besigye, a qualified physician who retired from Uganda’s military at the rank of colonel, is a former president of the Forum for Democratic Change party, for many years Uganda’s most prominent opposition group. He is a fierce critic of Museveni, for whom he once served as a military assistant and personal doctor.
