Former presidential candidate Hamdeen Sabahi described the constitutional declaration President Mohamed Mursi decreed on Thursday as a "coup on democracy and a monopoly of power".
The revolution "will not accept a new dictator", Sabahi added.
He also warned that such decisions will drive Egypt, which is seeking solutions for its problems, towards more problems.
