Results through on Tuesday showed that voters in Egypt voted overwhelmingly in favour of the constitution drafted by President Mohamed Mursi and his allies.
According to the final elections commissions figures, 63.8% of votes were cast in support of it.
Speaking to Reuters, Murad Ali of the Muslim Brotherhood's Freedom and Justice Party, said:
"I hope all national powers will now start working together now to build a new Egypt."
"I see this as the best constitution in Egypt's history."
Soon after the announcement, protesters who have rallied against the constitution took the streets once more.
Commenting on the on-going violence, a spokesperson for the State Department, Patrick Ventrell, said:
"President Mursi, as the democratically elected leader of Egypt, has a special responsibility to move forward in a way that recognises the urgent need to bridge divisions."
