Egypt's controversial proposed constitution has passed its two-part referendum with 63.8% of the vote, the country's election commission said today. The passage is a win for President Mohamed Morsi—whose Islamist allies drafted the constitution, sparking massive street protests—and is right in line with earlier unofficial results offered up by the Muslim Brotherhood, reports the AP. Opponents of the measure, however, have charged that the votes were marred by fraud. Nevertheless, "We have seriously investigated all the complaints," said judge Samir Abu el-Matti of the Supreme Election Committee today, according to Reuters. Official turnout was 32.9%.
