Egypt's new constitution, drafted by Islamist supporters of President Mohammed Morsi, has been approved by 63.8 percent of voters in a two-round referendum, the supreme election committee said on Tuesday.
The result, which followed votes held on Dec. 15 and on Dec. 22, matched an earlier unofficial tally given by Morsi's Muslim Brotherhood.
"We have seriously investigated all the complaints," judge Samir Abu el-Matti of the Supreme Election Committee told a news conference. The final official turnout was 32.9 percent.
