Egypt's election committee said on Wednesday it may not be ready to announce the results of a runoff presidential vote on Thursday as planned because it was still reviewing appeals from the two candidates, both of whom claim to have won.
The second round of the contest saw the Muslim Brotherhood's Mohamed Morsi fightfought a head-to-head contest with Ahmed Shafiq, the last prime minister of ousted president Hosni Mubarak.
The latest twist in the election came amid conflicting reports regarding the health of 84-year-old Mubarak. Late on Tuesday night it had been reported that he was "clinically dead". While this was swiftly retracted, it appeared early on Wednesday that his condition had deteriorated. Later reports suggested he had been taken off life support but would be monitored closely over the next three days after a stroke and cardiac arrest.
Preliminary results had placed the Muslim Brotherhood's candidate in the lead over Shafiq, a former air force commander regarded as the preferred choice of the country's ruling Supreme Council of the Armed Forces. However, the elections commission is still looking at hundreds of appeals from both camps that may strike some votes and tip the balance either way.
The Brotherhood had announced Morsi was the winner only hours after the polls closed. It released figures it had compiled from the 13,000 polling stations, giving Morsi 13.2m votes and Shafiq 12.3m.
The Shafiq campaign said its candidate was ahead but did not give initially give numbers. However, a member of the campaign, Tamir Wagih, told the Guardian their figures confirmed a Shafiq win. He said the Brotherhood's victory announcement was an attempt to incite violence in case their candidate lost.
"At that point only 30% had been counted, their announcement was a political trick to send a message to the military that if they don't win they will claim electoral fraud and justify acts of violence," he said.
Wagih also claimed the total number of voters in the runoff was 23.5 million, rather than the 25.5 million figure used by Morsi's supporters. The Shafiq campaign figures – which are not final – give their candidate 10.85m and Morsi 10.5m votes, with two million still to be counted.
If Morsi had won, Wagih said: "We respect the authorities and we'll discuss our response."
Any lengthy delay in announcing the winner risks prolonging uncertainty and stoking tension at a time when it is unclear how big a role the military will continue to play in leading the country.
On Tuesday, a US election monitoring group said it was unable to say whether the presidential election had been free and fair as it had not been given sufficient access. It accused the military leadership of hampering a transition to democracy.
The Carter Center criticised a court's decision to dissolve the Islamist-dominated parliament and issue a decree from the military council limiting the future president's powers.
