Zimbabwe's prime minister-designate Morgan Tsvangirai on Saturday said former South African president and mediator Thabo Mbeki had to show impartiality or the political power- sharing deal being negotiated would not materialize, dpa reported.
Addressing a Movement for Democratic Change (MDC) rally in a farming town of Marondera, about 70 kilometres east of Harare, Tsvangirai said: Mr Mbeki, there is only one message: when you have started a job finish it well."
Tsvangirai warned that "... the danger is that quite diplomacy has its limits," adding, "We will abandon it if we see that quite diplomacy is leading to quiet approval of wrong things."
The power-sharing deal for a government of unity entered between Tsvangirai and President Robert Mugabe on September 15 is deadlocked because of disagreements on the distribution of cabinet posts in the planned unity government.
Tsvangirai accuses Mugabe of taking all the 'key' ministries such as defence, information, home affairs, finance and foreign affairs.
Last week, Tsvangirai stayed away from a meeting in Swaziland of the security troika of the Southern African Development Community (SADC), saying he did not have the required travel documents.
The meeting has since been moved to Monday in Harare. Mbeki, the SADC mediator, was due to report back to the 15-member regional grouping on his failed attempt last week to end the deadlock.
Confirming that he would attend the meeting, Tsvangirai told his supporters: "When it comes to negotiations we fear no one. We have serious respect for SADC and African institutions, but they must learn to reciprocate that respect."
"We want this issue not to be solved beyond Africa. When they (SADC leaders) come on Monday we will show respect for them. We want to bring finality to this stupid thing. We want this deal to work for the people of Zimbabwe," he added.
The power-sharing deal is seen by many as the only way of rescuing Zimbabwe from economic meltdown. The once-prosperous nation now faces acute shortages of all essentials such as fuel, electricity, cash, food and drugs.
Inflation officially stands at more than 200 million per cent, though independent analysts put it at more than 1 billion per cent.
Tsvangirai also said at the rally that those responsible for the violence in the run-up to the controversial presidential election in June must face the wrath of law. Tsvangirai eventually withdrew from the race, allowing Mugabe to win an uncontested run-off vote.
The MDC says it lost more than 200 of its supporters to violence perpetrated by Mugabe's Zanu-PF party and its security agents.
