CAIRO: Many of Egypt's political powers, coalitions and political parties are calling for Mohamed el-Baradei to replace Essam Sharaf as Egypt's prime minister. They have decided to march from Tahrir Square to the Cabinet building and close Qasr el-Aini Street to prevent Sharaf and cabinet employees from entering or exiting the headquarters. Sharaf was appointed prime minister shortly after the resignation of Egypt's 30-year ruler, Hosni Mubarak, after 18 days of mass demonstrations. At the time, Sharaf was widely accepted by the people and viewed as a part of the January 25 Revolution that toppled Mubarak and his regime. Baradei, an expected presidential candidate, was a popular opposition figure during the last year of Mubarak's presidency. Formerly head of the U.N.'s nuclear watchdog, Baradei is widely respected both inside and out of Egypt. Demonstrators are calling for Baradei to be named prime minister and to form a new National Unity government. The Youth Revolution Coalition will hold a press conference at noon to announce the march to the cabinet and the group's decision to appoint Baradei as prime minister. The action comes in response to Sharaf's second major speech last night, which was not received by demonstrators or the youth coalitions. The coalitions will issue a statement ratified by all national powers in coordination with revolutionaries in Alexandria, Suez, Ismalia, and Port Said governorates.
