Thousands gathered in Tahrir Square to answer the call sent out to re-take the streets to “save the revolution”. A speech during Friday prayers conducted in the square centered on the unmet demands, including the trial of Mubarak, the formation of a presidential committee, the trial of all figures of corruption and the retrieval of the former ruling National Democratic Party's money. The preacher also criticized the presence of former NDP members in the national dialogue, arguing that reconciliation is unacceptable, a critique previously made by the Revolution Youth Coalition. Slogans and banners echoed the demands. Egypt's January 25 revolution had put forward several demands in addition to the end of Mubarak's rule, many of which have not yet been met, activists say. The call to restart demonstrations in Cairo's Tahrir Square was adopted by several political groups, including the Revolution Youth Coalition which had been criticized for its absence from the political scene. Coinciding with “Orphan's Day”, the Revolution Youth Coalition say that more than 120 families who have lost their children as martyrs during the revolution have been asked to join the planned demonstrations to condemn the late trials of those responsible for killing young demonstrators during the 18 day revolt. The revolution's unmet demands also include changing the constitution so as to mitigate the president's sweeping powers, dismantling the former ruling National Democratic Party, the trial of all corrupt figures including the ousted president Mubarak, ending the state of emergency, releasing political prisoners and lately many have been demanding an end to military prosecutions of civilians, after it had become a common phenomenon since the military took over power. Activists complain that the revolution is still far from successful in meeting its initial demands. Mubarak has not been put on trial and the NDP is still at work. Local councils and governors appointed by the old regime have not been replaced and editors of all the national papers, associated and hired by the old regime, remain in their positions. At the same time, members of the old regime still dominate most workers' unions and public companies. the emergency law has not been lifted and most political detainees remain in captivity. According to an Ahram Online correspondent the Muslim Brotherhood, Egypt's largest opposition group, were not noticeably represented in the square. Palestinian and Libyan flags were also waved around besides the Egyptian one.
