His spokesman Luke Tamborinyoka said Chamisa will be the acting president until Tsvangirai’s return.
Tsvangirai is reported to be critically ill in South Africa though he has rubbished the reports saying he is stable and recovering.
Tamborinyoka said Chamisa’s appointment is in light of the fact that the other two vice-presidents of the party Thokozani Khupe and Elias Mudzuri are both in South Africa.
Chamisa will also be the acting chairperson of the MDC Alliance.
Key negotiators for the MDC Alliance and the People’s Rainbow Coalition are reported to have gone to South Africa to negotiate setting up an opposition alliance to contest the Zimbabwe African National Union-Patriotic Front.-Insider
