A group of women activists will start a sit-in outside the Ittihadiya presidential palace on Tuesday as part of a series of events calling for the repeal of the protest law.
Nourhan Hefzy, the wife of Ahmed Douma, who was sentenced to three years in jail for breaking the protest law, said they would begin the sit-in by this evening, and there would be a march to the palace on 26 April.
Three prominent activists of the January 2011 revolution -- Ahmed Douma, Ahmed Maher and Mohamed Adel -- received three-year sentences and LE50,000 fines for breaking the protest law in December 2013.
Another prominent activist, Alaa Abdel-Fattah, is being tried on the same charge.
Thousands of others, mainly supporters of ousted Islamist president Mohamed Morsi, have been arrested during demonstrations.
Authorities say the protest law -- which was passed in November 2013 -- is necessary to quash Muslim Brotherhood protests, but it has been widely criticised by local and international rights groups.
The sit-in is a part of series of events against the protest law organised by The Way of the Revolution Front, an anti-military and anti-Muslim Brotherhood coalition, along with April 6 Youth Movement and a number of other youth movements and political parties.
