The official results of the three-day Egyptian presidential elections last week is expected to be announced by the electoral committee on Tuesday.
Former army chief Abdel Fattah al-Sisi is already being celebrated in the country as a clear winner, according to exit polls which saw him take the lead against his sole competitor leftist politician Hamdeen Sabbahi with 93 percent of the vote, Al Arabiya reported.
Egypt's elections committee rejected Sabbahi's appeal against voting results that gave Sisi a landslide victory, judicial sources said.
Sabahi's campaign sent a complaint to the elections committee on Friday objecting to what it said was "the existence of campaigning inside polling stations" by Sisi supporters, among other abuses.
It also appealed to the committee to nullify all votes cast on the third day of polling, which was introduced at the last minute of the second day of the vote on Tuesday in a surprise move to boost low turnout.
On Thursday, Sabahi conceded defeat but said the initial turnout figure of over 40 percent was too high and "an insult to the intelligence of Egyptians." However he said he will accept the final result of the vote.
The vote came 10 months after the army's ouster of elected Islamist President Mohammad Mursi in July in reaction to protests against his rule. Since then, Sisi has ridden of wave of popularity after having led Mursi's ouster.
