Egyptian leaders hold high hopes of a win for the new constitution, as voters turned out in large numbers, in what have been described as peaceful polls, on a referendum on the draft constitution.
With a higher turnout than expected, Mr Morsi predicted a win for the ratification of the constitution, shortly after polls closed at 11pm on Saturday.
The Muslim Brotherhood said that so far ballots were running 59% in favour of the constitution in about 86% of polling stations.
However main opposition strongholds of Cairo and Alexandria are yet to be counted.
The proposed constitution has caused renewed protest, violence and riots in Egypt with allegations that the draft allows for too much interference from religious authorities.
