Egypt's largest coalition supporting ousted Islamist president Mohamed Mursi has called on its supporters to rally on the fourth anniversary of the January 2011 uprising that toppled autocrat Hosni Mubarak.

"We demand the Egyptian people to be ready to continue their uprising that started in 2011, calling for the rights of bread, freedom and dignity," a statement by the coalition late Wednesday read.

The Muslim Brotherhood-led National Alliance to Support Legitimacy (NASL) is the sole coalition on the Egyptian political scene currently supporting the ousted Mursi.

Wednesday's statement highlighted that NASL is preparing for a campaign under the name "Egypt speaks revolution" in order to prepare a January 25, 2015 "uprising."

NASL has frequently staged small demonstrations in narrow streets across Egyptian cities, to avoid clashes with the police.

NASL members have also recently been calling for larger rallies. However, they almost always fail to draw crowds, often amid widespread apprehension of possible violence.

Their recent participation in what was dubbed an "Islamist Intifada" on 28 November was the latest failure in drawing significant crowds. The day of protest was initially called for by the ultra-conservative Salafist Front. 

Both NASL and the Muslim Brotherhood have been banned by the Egyptian authorities.
