Beyond the calls for Mubarak to resign, very little unites Egypt’s opposition parties, and so far they have struggled to produce leadership with clear aims for the day after. The most celebrated opposition figure, former head of the International Atomic Energy Agency, Mohamed el Baradei, is an experienced diplomat but an untested politician without a coherent political agenda to unite the public around him. Amro Musa, the Arab League General Secretary and former Foreign Minister, is another likely candidate, but he too lacks a popular support base. As for the leaders of the Muslim Brotherhood – outlawed and persecuted under the Mubarak regime – they have so far refrained from joining the protests for fear of being castigated as drivers of the revolution. But as the largest opposition block (they won 20% in the 2005 parliamentary elections), and with Mubarak’s imminent departure, they are likely to raise their profile and feature in whatever negotiations take place about the future governance of Egypt.
