HARARE, ZIMBABWE - Zimbabwe's opposition said Friday that it was willing to share power with the ruling party, but not with longtime President Robert Mugabe.

Left unresolved was whether a runoff election would be held. Mugabe said he was willing to take part in a second round of voting after official results showed him in second place.

The opposition Movement for Democratic Change was cool to the idea, however, saying a runoff could not be held now in a climate of violence and repression.

Earlier in the day, the Zimbabwe Electoral Commission released results from the presidential election March 29. They showed opposition leader Morgan Tsvangirai winning the most votes, but not the simple majority needed to avoid a runoff with Mugabe, who finished second.

Tsvangirai's deputy in the Movement for Democratic Change, Tendai Biti, acknowledged at a news conference that skipping a second round is a gamble that could result in another term for Mugabe, 84, who has ruled since Zimbabwe's independence in 1980.

Biti would not, as party leaders have done before, categorically rule out participating in a runoff. But he said there could not be one "for the simple and good reasons that that country is burning" amid violence and an economic collapse from rampant inflation.

The opposition maintains that a tally giving Tsvangirai anything but outright victory is fraudulent.

"Morgan Tsvangirai should be allowed to form a government of national healing that includes all Zimbabwean stakeholders," Biti told reporters in Johannesburg, South Africa. "The only condition we give ... is that President Mugabe must immediately concede."

He said that the party's top decision-making body would meet today to decide its next step, and that Tsvangirai would hold a news conference soon.

Biti said Mugabe's safety and that of his family and his assets would be guaranteed.

At a news conference in Harare, top Mugabe aide Emmerson Mnangagwa said the president has accepted the outcome and will run in the second round of balloting.
