A member of Egypt's Supreme Election Committee said complaints about a vote on the country's new constitution have been investigated.
The Committee said 63.8 percent of voters approved the new constitution following two polls this month, which took place amid accusations of fraud.
"We have seriously investigated all the complaints," judge Samir Abu el-Matti of the Supreme Election Committee told a news conference.
The result matched an earlier unofficial tally given by Mohamed Mursi's Muslim Brotherhood party.
The final official turnout was 32.9 percent.
