Tens of 'Rebel' campaigners collected signatures of no-confidence in President Mohamed Morsi from citizens passing by Cairo's Tahrir Square on Friday, Egyptian state news agency MENA reported.
Rebel members told MENA that they are ensuring their widespread presence in Tahrir on Friday of "Going Back to The Square" to collect the maximum number of votes in the million man march.
Earlier on Friday, protesters set up a stage in Mohamed Mahmoud Street in central Cairo in preparation for the demonstration.
Protesters also displayed pictures of slained protesters in the square's garden.
A number of political parties are participating in Friday's million man march, including the liberal Constitution Party and Free Egyptians Party, Socialist Popular Alliance, Nasserist Karama Party, The Popular Current, Black Bloc, Rebel, and Kefaya movement.
'Rebel' is a grassroots movement to register opposition to President Mohamed Morsi and force him to call early presidential elections by collecting 15 million signatures by 30 June.
Officially launched on 1 May, the group said it has collected more than two million signatures in the first 10 days.
