Conservative Islamist group threatens to join a million-man march in Cairo on 18 November if Egypt's interim government fails to withdraw its controversial plans to change the constitution Egypt's conservative Islamist group, Al-Gama'a Al-Islamiya, has threatened to take part in protests in Tahrir Square planned for 18 November if the government does not withdraw the proposal for Supra-Constitutional principles made by deputy minister of political affairs Ali El-Salmi. On Friday, the Islamist group issued a statement calling on the ruling Supreme Council of the Armed Forces (SCAF) to distance itself from El-Salmi's document. It described the government's proposal, issued on Tuesday, as "a suspicious attempt" to turn the people against the army. The group reminded SCAF of its previous promise to hand over power to an elected civilian authority, saying properly carrying out this pledge would force SCAF to reject the Supra-Constitutional document. Many political powers and parties have also rejected the document, including the Muslim Brotherhood and other Islamic groups. Rejectionists have threatened to participate in a 'million man march' in Cairo's central square in two weeks' time, if the government fails to withdraw its proposals.
