Secretary-General of the Presidential Electoral Commission Hatem Bagato said the commission will announce the results of Egypt's presidential runoff elections at 3pm (1pm GMT) Sunday, according to Egyptian state TV.
Both Muslim Brotherhood candidate Mohamed Morsi and Mubarak's last premier Ahmed Shafiq have claimed victory, citing their unofficial counts.
The electoral commission was supposed to announce the results on Thursday but decided to delay the announcement in order to examine appeals presented by both candidates.
Earlier reports claimed that the commission would announce the results of the second round run-off Saturday evening, but the Presidential Commission denied the reports.
Sultan said the commission is still in the process of assessing complaints filed against the results in certain polling stations. He added that the date of announcing the results will only be specified when the commission has obtained the final results having examined all the complaints.
