Egypt's new vice president announced a fresh list of political concessions Sunday after meeting with opposition groups, including a plan to amend the constitution and guarantees to honor freedom of the press and communications. The agreements, which were reported by Egyptian state television, resulted from talks between Vice President Omar Suleiman and a variety of opposition factions, including the Muslim Brotherhood, the Islamist movement that is officially banned in Egypt. It remained unclear, however, whether the concessions would win favor in Tahrir Square, the plaza in the heart of Cairo where tens of thousands of demonstrators have gathered for nearly two weeks to demand the ouster of President Hosni Mubarak. Many of the protesters there have insisted that Mubarak quit before they will agree to stand down. They have also distanced themselves from the political party leaders and intellectuals that have negotiated with Suleiman over the past two days, saying that they do not adequately represent the grass-roots uprising that has pushed Egypt to the brink of revolution. "My bet is, the crowd is not going away," said Hisham Kassem, a political analyst and journalist who has opposed Mubarak's rule for years. He said the parties that have been in talks with Suleiman "are all completely irrelevant," adding, "the people on Tahrir Square either wouldn't recognize them, or else would barely give them the time of day."
