South Africa's new government has called on Thabo Mbeki to continue mediating in Zimbabwe's political crisis. He brokered a power-sharing deal in that country last month, but his role was thrown into doubt after South Africa's ruling ANC forced him to resign days later, Reuters reported.

Pressure for the former South African leader to become involved again has grown as Mugabe's party and the opposition have reached deadlock over the allocation of posts in a unity government to be set up under the September 15 deal.
The impasse threatens to delay efforts to revive Zimbabwe's shattered economy, suffering inflation of about 11 million percent and widespread shortages of food and fuel.
"Mr. Mbeki's facilitation efforts in Zimbabwe have proven his dispassionate vision for a lasting political solution to the challenges facing Zimbabwe," new South African President Kgalema Motlanthe said in a statement.
"Accordingly, our government has full confidence in Mr. Mbeki's ability to build on the historic successes already made in the power sharing negotiations under his mediation."
Morgan Tsvangirai's Movement for Democratic Change initially criticised Mbeki as being too soft on Mugabe, but it now supports him continuing his 18-month mediation under a mandate from the 15-nation Southern African Development Community.
Mugabe's ZANU-PF, which lost control of parliament in a March election, said it did not see any immediate need for mediation over the dispute on cabinet posts.
"I don't think that the issue of allocation of ministries is a matter that can be referred to the facilitator (Mbeki)," Patrick Chinamasa, chief ZANU-PF negotiator at the talks, was quoted as saying in the state-run Chronicle newspaper.
"We cannot, at the slightest difference in opinion, call outsiders to mediate. If there is thinking on such kind of an approach, it has to stop in the interest of harmonisation of relations," Chinamasa said.
