The leader of the Movement for Democratic Change is 2% short of the 50% required to avoid a run-off against President Mugabe.
Tsvangirai's Movement for Democratic change has presented its own figures claiming the party won 50.3% and has refused to concede the need for a run-off.
President Mugabe has already been endorsed by his Zanu-PF party to participate in a second round of voting although he has not made any comment on whether he will stand.
The opposition and human rights groups have accused the authorities of waging a campaign of violence to ensure that Mugabe would win a second vote.
