A number of liberal politicians withdrew on Sunday from the Islamist-dominated assembly drafting Egypt’s new constitution, saying they were not given the opportunity to discuss articles and their suggestions were being ignored.

The departure of at least 12 liberals from the 100 member assembly follows the resignation of five Christian delegates – as well eight out of 10 members of a advisory committee providing technical assistance – over similar complaints.

The constitution is a cornerstone in Egypt’s democratic transition after the uprising that ousted Hosni Mubarak last year. Without it, the country cannot hold elections to replace a parliament that a court declared void in June.

But bickering between Islamists and liberals over subjects such as the role of Islam in politics, civic freedoms and women’s rights has delayed voting on articles in the charter.
