A delegation from Egypt's "Rebel" campaign group is going to meet with Interim President Adly Mansour on Sunday at the presidential palace, the campaign announced on its website.

The meeting will be aimed at discussing the roadmap for the transitional phase, the formation of the next cabinet, and some of the details of the the army statement that ousted President Mohamed Mursi with the interim president.

The "Rebel" campaign representatives who are going  attend the meeting are the spokesman of the campaign, Mahmoud Badr and two of its founding members; Mohamed Abdel-Aziz and Hassan Shahin.

On Wednesday, Egypt’s top army commander Abdel Fattah al-Sisi said that the army has agreed with political forces to suspend the constitution and delegate the head of the constitutional court as an interim president until early presidential elections are held.

The Rebel campaign is widely credited for its role in collecting signatures against the ousted president and mobilising for the mass protests that resulted in his removal.

The campaign urged the people to take the streets again on Sunday to "continue the revolution".
