HARARE (Reuters) - South African President Thabo Mbeki willmeet Zimbabwe's rival parties in Harare on Monday amid growingdoubts over his chances of securing a power-sharing deal to endthe political crisis.
Opposition leader Morgan Tsvangirai said on Sunday he wouldrather quit talks than sign a bad deal and challenged PresidentRobert Mugabe to hold a new election. Mugabe had threatened toform a government alone if Tsvangirai did not sign a deal lastweek.
The post-election talks are deadlocked over how to shareexecutive power between Mugabe and Tsvangirai, putting off anychance of rescuing Zimbabwe from its economic collapse.
South African Ministry of Foreign Affairs spokesman RonnieMamoepa said Mbeki would meet the leaders of Zimbabwe'snegotiating parties in Harare.
Tsvangirai beat Mugabe in a March 29 election but fellshort of enough votes to avoid a June run-off, which was won byMugabe unopposed after Tsvangirai pulled out, citing violenceand intimidation against his supporters.
Mbeki, mandated by regional countries to mediate in theZimbabwe talks, has come under repeated fire for not beingtough enough with Mugabe.
Other southern African leaders have taken a harder lineagainst Mugabe, but he has refused to budge, and Tsvangirai'sMovement for Democratic Change (MDC) has made it clear it haslittle faith in Mbeki as a mediator.
Tsvangirai told a rally on Sunday marking the party's ninthanniversary that he would not change his position in thepower-sharing talks if pressured by Mbeki.
In a commentary in Monday's edition of the government-runHerald newspaper, its political and features editor Mabasa Sasaagain accused Tsvangirai of refusing to sign a final deal onorders from Western powers opposed to Mugabe.
"The short history of the opposition is littered withevidence of a cancerous connection with Britain and otherWestern countries," he said, urging Mugabe to appoint a newcabinet to tackle Zimbabwe's worsening economy.
Mugabe's victory in the election run-off was condemnedaround the world and drew toughened sanctions from Westerncountries whose support is vital for reviving Zimbabwe's ruinedeconomy.
A smaller, breakaway faction of the MDC, led by ArthurMutambara, is the third party in negotiations aimed at forminga national unity government.
Tsvangirai told the rally an agreement was out of thequestion unless Mugabe, in power since independence fromBritain in 1980, was prepared to compromise.
