The Free Egyptians party is against a handover of power to the People's Assembly (parliament's lower house), Mohamed Abou Hamed, the head of the party's parliamentarians told Ahram Online.
Abou Hamed joined the Mostafa Mahmoud march to Tahrir Square to demand the ruling military council hand over power.
The parliamentarian went on to clarify that his opposition stems from a wariness of the Assembly's Islamist majority. Abou Hamed believes instead that presidential elections should be brought forward.
The Free Egyptians, founded by prominent Coptic Christian business tycoon Naguib Sawiris, competed in the lower house elections alongside a coalition of parties called the Egyptian Bloc, which won 33 seats.
