Early unofficial results suggested more than 60% of voters said "yes" to the document, which is endorsed¹ by Islamist President Mohammed Morsi.

 

But the opposition², which says the draft favours Islamists, is demanding an inquiry³ into alleged⁴ voting fraud.

 

Egypt has seen large and occasionally violent demonstrations⁵ by the opposing sides in the past few weeks.

 

If the constitution passes, elections must take place within three months and the deep polarisation（偏振，分化） in the country is likely to continue, the BBC's Bethany Bell in Cairo reports.

 

In the meantime, legislative⁶ powers would remain with President Morsi.

 

 

State media reports of the results following Saturday's second and final round of the referendum suggest that some 63% of voters had backed the charter. Turnout was low, estimated at 30%.

 

But the opposition National Salvation⁷ Front said on Sunday the vote had been marred⁸ by "fraud and violations⁹".

 

These included polling stations opening late and Islamists seeking to influence voters, they said.

 

Spokesman Amr Hamzawy told a news conference the front as "asking the commission to investigate the irregularities before announcing official results".

 

However, another spokesman, Khaled Daoud, told the BBC the front would not contest the result.

 

The group has complained that there was not enough legal supervision¹⁰ of the referendum, after many judges boycotted¹¹ the process.
