Ahmed Shafik, who served as Egyptian prime minister under Hosni Mubarak, will be announced as the winner of the country's presidential runoff election on Sunday evening, Egpytian daily Al-Ahram reported Friday, citing government sources.

Al-Ahram quoted a source in the current Egyptian government as saying Shafik will be declared victor with 50.7 percent of the vote.

Both Shafik and rival candidate Mohamed Morsy of the Muslim Brotherhood have previously declared themselves the winner of the runoff election.

The results of the election were originally scheduled to be announced on Thursday, but the announcement was delayed as Egypt's electoral commission investigated charges of fraud lodged by both sides.
