On Sunday the Muslim Brotherhood's Freedom and Justice Party warned Egypt's ruling military council that postponing parliamentary elections would lead to another revolution.
Delaying elections without putting the issue to a referendum would constitute a military coup, the party said.
In a post on Twitter, party Secretary General Mohamed Saad al-Katatny said, "The coming days represent a decisive stage for the revolution. If the dates of parliamentary and presidential elections are not announced or if the elections are delayed, then we will have had an unfinished revolution."
Azab Mostafa, a senior member of the party, said the party believes the entire parliament should be elected through the list-based candidacy system, a demand of all parties in the Democratic Coalition.
If the Supreme Council of the Armed Forces (SCAF) doesn't announce the schedule for elections before the end of September it will no longer have legitimacy, because it previously said it would stay in power for six months, Mostafa said.
Ahmed Abu Baraka, legal adviser to the party, said no entity has the right to violate the Interim Constitution.
Emad Abdel Ghafour, president of the Salafi-led Nour Party, said his party and other political powers will not remain silent if the elections are delayed.
Mamdouh Ismail, vice president of the Salafi-led Asala Party, said foreign powers want the elections postponed over fears that Islamists will seize a majority in parliament in the coming elections.
“Our response will be strong if the elections are postponed,” he said.
