Zimbabwe's ruling party hopes a second-round runoff between President Robert Mugabe and challenger Morgan Tsvangirai will take place as soon as possible.
The opposition leader said today he would contest a presidential runoff poll, but called for it to take place on 23 May in accordance with the law.
Results from the first round were delayed by five weeks and no date has been given for the second-round runoff despite the legal requirement for it to take place within 21 days of the first-round results being announced.
First-round results were published on 2 May but electoral officials have hinted that a second round could take up to a year to organise.
Mr Tsvangirai had previously refused to say whether he would take part in a runoff, and also claimed he had won an outright majority in the first round.
