The National Salvation Front and its members did not receive an official invitation from Egypt's presidency to attend national dialogue, a front spokesman said.
A flood of initiatives poured on us since a court order halted the election process yet we are still waiting for an official invitation, spokesman Khaled Dawood told Aswat Masriya.
We welcome the dialogue but we have clear demands and agenda which include reshuffling the cabinet, sacking the chief public prosecutor, forming a committee to amend the constitution and amending the election law, Dawood said.
"The presidency is not serious about any invitation for dialogue."
The oppositionist National Salvation Front announced in January it will boycott the upcoming elections if President Mohamed Mursi did not respond to its demands.
