Cairo: Egypt`s National Salvation Front, a coalition of the country`s largest liberal-democratic parties and movements, has officially rejected talks proposed by President Mohamed Morsi.
Morsi addressed Egyptians Thursday urging a national dialogue between all political forces, but the opposition said the president had not offered enough concessions.
Instead, Morsi`s opponents said they would take to the capital`s streets to protest the president`s recently expanded powers, Saudi-owned news channel Al Arabiya reported.
Two other opposition groups said they would also boycott the talks, BBC reported citing state media.
Morsi`s Nov 22 constitutional declaration expanded his executive authority by barring the courts from challenging his decisions. Egypt`s highest judicial authority, the Supreme Judicial Council, earlier called Morsi`s move "an unprecedented attack on the independence of the judiciary and its rulings".
Opposition groups have been rallying against the constitutional declaration and Morsi`s decision to hold a nationwide referendum on the new Constitution Dec 15, which they described as too hasty.
Earlier this week, violent clashes between Morsi`s supporters and opponents left five people dead and hundreds injured.
