In President Robert Mugabe's first waiver of power in nearly 30 years, the agreement outlines six executive posts to be led by the veteran leader and a new prime minister, Morgan Tsvangirai, head of the opposition Movement for Democratic Change (MDC). Each will have two deputies.
The former bitter rivals committed themselves to free political activity, a national healing process and the restoration of economic stability in a country that was once a regional breadbasket.
The all inclusive power-sharing agreement will see 31 ministers drawn from Zimbabwe's three main parties, with Mugabe's ZANU-PF saying on national television late Monday that talks to allocate the posts would begin Tuesday.
