Mugabe party demands poll recount
The state-run Sunday Mail newspaper said the governing Zanu-PF party requested a recount because there had been "errors and miscalculations".
The paper also quoted a senior minister as saying it had rejected an opposition approach to form a unity government.
On Saturday, the opposition accused President Mugabe of "preparing a war".
Movement for Democratic Change (MDC) leader Morgan Tsvangirai warned that "militants are being rehabilitated" and troops deployed ahead of a possible second round run-off in the presidential poll, which he insists he won.
Mr Tsvangirai also claimed that the country's central bank was printing money "for the finance of violence".
He called on Mr Mugabe to enter a dialogue to prepare for a peaceful transition.
