HARARE, Zimbabwe (CNN) -- A power-sharing deal has been reached between Zimbabwean President Robert Mugabe and the opposition Movement for Democratic Change, said South African President Thabo Mbeki.Mugabe (left) and Tsvangirai
Mbeki, who mediated the talks in Harare for the Southern African Development Community, said the deal would be signed Monday but did not give details of the agreement.
Zimbabwe has had no Cabinet since the March presidential election that started the impasse.
Opposition lawmakers booed and heckled Mugabe when he spoke at the opening of the country's parliament on August 26.
MDC leader Morgan Tsvangirai won the most votes in that election, but not enough to avoid a runoff, according to the government's official count.
He withdrew from the June 27 runoff days before the vote, saying Mugabe's supporters had waged a campaign of violence and intimidation against opposition supporters.
The main sticking point in the talks had been how much power Mugabe would retain.
Tsvangirai had said he would sign a deal only if Mugabe gave up some power and his presidency became a ceremonial position.
The country is also reeling from hyper-inflation. In August the country's Central Statistical Office said inflation was at 11.2 million percent, the highest in the world.
Analysts have said the Zimbabwean government's official inflation rate figures are conservative.
One of Zimbabwe's leading banks, Kingdom Bank, said the country's inflation rate was more than 20 million percent.
The economic crisis has destroyed Zimbabwe's currency and made it difficult for Zimbabweans to buy basic commodities, electricity, fuel, and medicines.
