Egyptian President Hosni Mubarak resigned as head of Egypt's ruling National Democratic Party (NDP) on Saturday, state television said.

The executive committee of the NDP also resigned Saturday, including Mubarak's son Gamal Mubarak, according to state TV.

Hossam Badrawy replaced both Safwat el Sherif and Gamal Mubarak as Secretary General and Policy Secretariat of the NDP. Badrawy is a prominent physician and well known politician. He graduated from the School of Medicine at Cairo University in 1974 and has been part of the liberal wing of the NDP.

The military, which is crucial to decide whether the embattled president to step down, has so far given no hint of its stance as the demonstration entered the 12th day.

Earlier on Saturday, Egyptian army commander Hassan al-Roweny went to the Tahrir, or Liberation, Square, in downtown Cairo to persuade thousands of protestors to stop the demonstration and keep the society from being more chaotic.

The senior officer said in a loud speaker that the crowd should go home and the army guaranteed the safety of protestors, a Xinhua reporter said. The address was responded with shouts from demonstrators.
