Tsvangirai

Mr Tsvangirai's death in 2018 prompted further schisms.

The opposition has a history of division, dating back to 2005 when the MDC split, when Morgan Tsvangirai was in charge, over disagreements about whether to participate in senatorial elections.

Mr Chamisa says Mr Tsvangirai appointed him acting leader from his hospital bed.

But it was regarded as unconstitutional as Tsvangirai's deputy, Thokozani Khupe, was the rightful successor.

This pushed then President Robert Mugabe into agreeing a historic power-sharing deal with his long-time rival, Morgan Tsvangirai.
