(CNN) -- Embattled Zimbabwean President Robert Mugabe signed a power-sharing deal with the opposition party's breakaway faction, his party said Tuesday, though Mugabe's opponents denied the claim. Zimbabwe President Robert Mugabe leaves a hotel where negotiations had been taking place Tuesday. Mugabe's party said the deal, which promises cabinet positions to the splinter group of the Movement for Democratic Change, does not involve MDC head Morgan Tsvangirai. Tsvangirai said he still is involved with the talks, and that the power-sharing deal with the MDC offshoot is part of larger deal that has not been signed by anyone. Welshman Ncube, spokesman for the MDC splinter group, also said his party has not signed a deal with Mugabe, though Mugabe's party said the deal was signed with the group's chief, Arthur Mutambara.

Another high-ranking official with knowledge of the negotiations told CNN that the deal signed with @placeholder, head of the faction that broke from the MDC, has to do with the prime minister position that will be created in the new Zimbabwe government.

But @placeholder has sought to keep control of both and make the prime minister position "ceremonial," the official said.

Tsvangirai had been in power-sharing talks with Mugabe in recent days as a culmination of his party's protest of @placeholder's disputed re-election in a June presidential runoff.
