A senior leader of ousted Islamist President Mohammad Morsi's party called for mass rallies across Egypt on Monday, hours after tens of thousands of supporters demanded his return in a peaceful protest in Cairo.
Interim Prime Minister Hazem el-Beblawi is expected to swear in a new cabinet next week to enforce an army-backed "road map" to restore civilian rule. The military overthrew Morsi, the country's first democratically elected president, on July 3.
Morsi's party has rejected all political process since then.
"Next Monday a bigger crowd, God willing, in all the squares of Egypt - against the military coup," Essam El-Erian, Brotherhood's Freedom and Justice Party, said on his Facebook page on Saturday.
"Egypt decides through the ballot box, through protests, and mass rallies and peaceful sit-ins. No one person, one elite group and military organisation will impose its decision on the people," he said.
