The Commission reported Friday the Zanu-PF party won 142 of 210 seats in parliament, enough to make changes in the national constitution.
Results of the presidential race between Mugabe, 89, who has been president since 1980, and opposition leader and Prime Minister Robert Tsvangirai, have yet to be announced, the BBC reported Friday.
The head of the African Union's observer mission said Friday the presidential and parliamentary elections were free and credible. Olusegun Obasanjo said certain "incidents" reported during Wednesday's polling could not "change the outcome" even though the largest observer group called the elections "seriously compromised," the BBC reported.
After predicting "a landslide victory" to the state-run newspaper The Herald, Mugabe claimed victory for his party in an election Tsvangirai called a "huge farce."
Obasanjo, speaking in Harare, said the elections were "free, honest and credible."
He said there were "incidents that could have been avoided," but stressed African Union monitors did not think they would change the elections' overall outcome, the BBC said.
The "incidents" were not described.
