Opposition forces organized marches to Egypt's presidential palace and Tahrir Square on Tuesday against a constitution written by an Islamist-dominated assembly.
The controversial charter is currently being put to a referendum despite outrage from opposition groups who feel it does not represent all Egyptians.
Two marches, one from Nour Mosque and the other from Rabaa al-Adaweya Mosque, will go to the president's palace, while another two will take off from Shubra and Mohandseen to head to Tahrir.
All marches will move at 4 p.m. to express rejection to the draft constitution that Islamists argue is essential for the country to move forward towards stability and democracy.
Liberal and leftist political parties will participate in the demonstrations along with the April 6 youth movement and other revolutionary groups.
