Morsi's palace surrounded as protesters call for 'downfall of the regime' We are going to use any possible, civil means to send a message to both the president and the international community. As tear gas swirled overhead, Maryam Samy, 25, a telecommunications engineer, said: "The new constitution has no compromise. They want to apply their own standards of freedom, which is not freedom. This constitution is worse than the Mubarak constitution. It was better under the military - we could all rebel against the military but the Brotherhood are using the poor and religion to divide society. The rally provided a stark illustration of the dividing line that has cut across revolutionary Egypt. Saturday's marches by the Muslim Brotherhood also mustered hundreds of thousands, largely bussed in from the suburbs and the conservative provincial towns that provide the Brotherhood's base. Yesterday's crowd was younger and more modern, with hardly any of the galabiyas, traditional Egyptian male tunics, or niqabs, full face-veils, that were widely on display on Saturday. Instead there were thousands of women, many not even wearing the head-scarf, as well as fashionably dressed young men. Many were dismissive of the Brotherhood's supporters. Ali Sisy, the deputy editor of Masry al-Youm, one of the main liberal newspapers, said bluntly: "This is a conflict between ignorance and civilisation." The Brotherhood insists the constitution contains basic rights and freedoms, including of speech and belief, as well as recognising Egypt's traditional, Muslim culture. It also says the referendum, set for December 15, will end Mr Morsi's self-proclaimed powers to act without judicial oversight on "sovereign matters." It also accuses opposition leaders like Mr ElBaradei of being responsible for the impasse, since they have refused to meet Mr Morsi until he backs down on those powers. "We're glad Egyptians are able to express opinion freely and hopefully peacefully," the Brotherhood's website said. Ballot box to decide outcome.
