The Islamist-dominated assembly that wrote Egypt's new constitution has invited four of the leaders of the National Salvation Front for a public dialogue on Friday.
The assembly's board said that it sent invitations to Mohamed ElBaradei, Amr Moussa, Hamdeen Sabahi and Sayed al-Badawy.
The National Salvation Front - Egypt's main opposition coalition - had announced its rejection to the referendum on the constitution that is written by the assembly, calling on people to vote against it.
Opposition forces argue that the controversial charter does not represent all Egyptians while Islamists insist that passing it would help implement stability.
The assembly said that the dialogue comes as an attempt to present all views democratically and with transparency so that individuals can make informed decisions on their own.
The assembly insisted that the dialogue will reflect the political forces' keenness on national interest.
The first round of the referendum took place on Saturday, December 15, while the second is scheduled for December 22.
