South African President Jacob Zuma meanwhile, was expected in Harare Friday for a meeting with Mr. Mugabe and Tsvangirai over ongoing disagreements in the unity government.
Zimbabwean Prime Minister Morgan Tsvangirai has filed a Supreme Court challenge against President Robert Mugabe's unilateral appointment of the country's 10 provincial governors.
In papers file Wednesday Mr. Tsvangirai wants the court to nullify the appointments, which he describes as illegal.
The MDC leader accuses Mr. Mugabe of violating the Constitution and the Global Political Agreement by not consulting him over the appointments.
But President Mugabe has insisted before that the appointments were legal.
Tsvangirai spokesman Luke Tamborinyoka told VOA Studio 7 reporter Jonga Kandemiiri that his boss has the same rights as any citizen to approach the courts.
Meanwhile, South African President Jacob Zuma is expected in Harare Friday for a meeting with Mr. Mugabe and Tsvangirai over ongoing disagreements in the unity government.
Mr. Zuma’s visit comes a week after the SADC Troika on Politics, Defense and Security failed to discuss Harare's deepening crisis in Botswana.
Political analyst and Centre for Research and Development Executive Director Farai Maguwu told VOA Studio 7 reporter Jonga Kandemiiri that Mr. Zuma’s visit will do little to change President Mugabe’s stance on the so-called outstanding issues.
