The 15-nation Southern African Development Community (SADC) said in a resolution Zimbabwe's squabbling political parties should form a unity government to restore peace, Reuters news agency reported.

Morgan Tsvangirai of the opposition Movement for Democratic Change said he was "shocked and saddened" by the outcome of the summit. It brought together leaders and ministers of SADC countries for more than 12 hours of talks on Zimbabwe's political impasse and the violence in eastern Congo.

"The MDC is shocked and saddened that SADC summit has failed to tackle these key issues ... a great opportunity has been missed by SADC to bring an end to the Zimbabwean crisis," Tsvangirai said at a post-summit news conference.

SADC said Tsvangirai did not agree with SADC's call for his MDC to co-manage Zimbabwe's Home Affairs Ministry with President Robert Mugabe's ruling ZANU-PF.
The resolution calling for joint control of the ministry - which controls Zimbabwe's police and is the main sticking point in the talks - was backed by all 15 members of SADC, said Arthur Mutambara, leader of a breakaway MDC faction. The SADC said a unity government must be formed.

"We need to form an inclusive government, today or tomorrow," SADC Executive Secretary Tomaz Salamao told reporters late on Sunday night after the summit in South Africa. "... SADC was asked to rule and SADC took a decision and that's the position of SADC. Now it's up to the parties to implement," he said.

Regional instability

Mugabe, in power since 1980, appeared optimistic that an agreement could be reached but Tsvangirai warned of regional instability if the ruling party refused to loosen what he called its illegitimate grip on power.

The old foes have been deadlocked over allocation of important cabinet positions since the September 15 deal, which Zimbabweans hoped would produce a united leadership to revive the ruined economy in the country where inflation is the world's highest and food and fuel shortages widespread.

Tsvangirai said co-managing the ministry with the ruling party was unworkable, citing the party's contempt for the MDC. He said SADC lacked the "courage and decency to look Robert Mugabe in the eyes" and tell him his position was wrong.

Highlighting growing regional impatience, South African President Kgalema Motlanthe said earlier on Sunday the deal offered the only hope for Zimbabwe to ease the economic crisis. Past SADC meetings have failed to produce a breakthrough.
