JOHANNESBURG, Oct. 12 (Xinhua) -- Former South African President Thabo Mbeki's spokesman said on Sunday that Mbeki left for Harare in a bid to resurrect power-sharing talks.

    Talks on implementing a stalled September 15 agreement were branded dead in the water on Sunday by opposition leaders soured by Zimbabwean President Robert Mugabe's weekend decision to award key posts to his ruling party.

    Nelson Chamisa, spokesman for the main Morgan Tsvangirai-led Movement for Democratic Change, made a passionate appeal to Mbeki and the 15-member regional bloc Southern African Development Community (SADC) that appointed him to help resolve the latest crisis.

    "Mr Mbeki, please help Zimbabwe. We need your help. We also need the help of and support of the SADC," Chamisa told SA FM radio.
