By NBC News staff and wire reportsCAIRO - A constitution drafted by an Islamist-dominated assembly was approved by a majority of Egyptians in a referendum, rival camps said on Sunday.
The Muslim Brotherhood, which propelled President Mohamed Mursi to power in a June election, said 64 percent of voters backed the charter after two rounds of voting that ended with a final ballot on Saturday. It cited an unofficial tally.
An opposition official also told Reuters their unofficial count showed the result was a "yes" vote.
Official results are not expected until Monday. If the outcome is confirmed, a parliamentary election will follow in about two months.
Mursi's Islamist backers say the constitution is vital for the transition to democracy, nearly two years after the overthrow of autocrat Hosni Mubarak in an uprising. It will provide stability needed to help a fragile economy, they say.
