He said the 15-nation Southern African Development Community (SADC) "remains seized with the enormous responsibility of ensuring that the parties signatory" to the February agreement "move rapidly towards its full implementation".

Tsvangirai was speaking at a press conference on the sidelines of a SADC summit in the Democratic Republic of Congo capital Kinshasa, adding that he was attending the summit in his capacity as leader of the former opposition Movement for Democratic Change party.

"Now that the SADC Troika is specifically vested with the matter of Zimbabwe it is my hope and belief that it will deal with all outstanding issues as a matter of urgency," he said

Tsvangirai’s MDC and long-time rival President Robert Mugabe’s Zanu-PF signed a deal to form a unity government in February but the parties have clashed openly over the appointment of a Central Bank chief and chief prosecutor.

Meanwhile in South Africa, the Movement for Democratic Change (MDC) representatives have called on the Southern African Development Community to proceed swiftly towards the full implementation of the global political agreement (GPA).

The party handed over a petition at the Democratic Republic of Congo (DRC) embassy in Pretoria on Tuesday.

The GPA is an agreement signed between Zimbabwe’s three main political parties, aimed at providing a map for the way forward. The agreement was signed on September 15, last year.

MDC spokesperson Sibanengi Dube said the party wanted the new chairman of SADC who is also the leader of the DRC Joseph Kabila, to investigate violence in Zimbabwe and make the 2002 report on violence public.

He said the MDC also wanted a report from the SADC mediation team to be tabled and for the SADC to clarify its role in mediation.

"We are not sure whether former president Thabo Mbeki is still a mediator…we want clarity on that," he said. Key to the demand was the appointment of the governor of the reserve bank and the attorney general, which, he charged, President Robert Mugabe had made illegally.

"We still hope SADC will help to resolve problems in Zimbabwe," he said.

The petition handover was organised by the MDC SA along with the Crisis Coalition of Zimbabwe and the Zimbabwe Solidarity Forum.
