Election body says that 38.6 percent of country's more than 53 million eligible voters took part in two-day polls, Aljazeera reported.
Egypt's election committee says 98.1 percent of voters have approved a new, military-backed constitution in the first vote since a coup toppled President Mohamed Morsi.
Egypt's High Election Commission said on Saturday that 38.6 percent of the country's more than 53 million eligible voters took part in the two-day poll.
That's 20.5 million voters casting ballots.
This is the first vote since the military removed Egypt's first freely elected president, Mohamed Morsi, following massive protests in July.
