Former Egyptian army chief Abdel Fattah al-Sisi won a landslide victory in a presidential election on May 29 but a low turnout may have deprived him of the strong mandate he needs to fix the economy and face down an Islamist insurgency.

Sisi won 93.3 percent of votes cast, judicial sources said, with most ballots counted after three days of voting. His only rival, leftist politician Hamdeen Sabahi, gained 3 percent while 3.7 percent of votes were declared void.

Turnout was about 46 percent of Egypt's 54 million voters, the government said, less than the 40 million votes, or 80 percent of the electorate, that Sisi had called for last week.

It was also less than the 52 percent turnout secured in the 2012 presidential election by Mohamed Mursi, the Islamist leader Sisi ousted last year after mass protests against his rule.
