Islamist parties continue their winning streak in Egypt's elections.

The Muslim Brotherhood's Justice and Freedom Party won 58 percent of the seats in the upper parliament, and the al-Nour Party garnered another 25 percent.

Egypt's upper parliament has no legislative powers, but it serves in a consultant role.

Last month, Islamists won sweeping majorities in the lower house.

Meanwhile, the interim ruling military council announced plans to appoint a 100-member panel to draft a new constitution before it steps down.

The selection process, which will begin March 3, will include politicians, legal experts, academics and other professionals.

A central issue in the new constitution promises to be the role Islam will play in Egypt's new government.

The present constitution names Islam as the state's predominant religion and legislation in principle is founded on Sharia law. Islamist parties may want the new constitution to state that legislation is founded solely on Sharia.
