Egypt's liberal opposition has called for more protests on Sunday after the president made concessions overnight that fell short of their demands to rescind a draft constitution going to a referendum on Dec. 15.

Morsi met one of the opposition's demands overnight, rescinding his Nov. 22 decrees that gave him near unrestricted powers. But he insisted on going ahead with the referendum on a constitution adopted by his Islamist allies.

The opposition National Salvation Front called on supporters to rally Sunday against the referendum.
