A majority of Egyptian voters approved a new draft constitution in referendum, unofficial results showed Sunday.
State television said unofficial tallies showed that 63.5 per cent of the ballots cast in the two-stage vote favoured of the charter, dpa reported.
Nearly 71 per cent of those who voted in Saturday's final phase of the referendum approved the draft, the broadcaster said.
No specific date has been set yet for the official results.
President Mohammed Morsi's Muslim Brotherhood and its Islamist allies said the charter will fast-track the transition to democracy from the authoritarian rule of president Hosny Mubarak, who was ousted nearly two years ago.
The opposition said the draft charter of an Islamist-led constituent assembly could undermine political rights and sideline minorities.
Supporters and opponents have been engaged in street fighting in recent weeks, triggering worries about civil strife in the Arab world's most-populous country.
Approval of the proposed constitution clears the way for legislative elections within 60 days. The Islamist-dominated Shura Council, or upper house, will be given the authority to legislate until a new legislature is elected.
