Morsi's supporters, including his Islamist allies, remain steadfast in their rejection of the popularly supported military coup that toppled Morsi nearly two weeks ago.
They have staged a series of mass protests in Cairo to push their demands, and are vowing to stay in the streets until Morsi is returned to office.
Speaking at a mass rally staged by Morsi's Muslim Brotherhood in Cairo, the two dozen former parliamentarians, all Islamist members of the Shura Council that was dissolved by court order, accused the military of attempting to restore a "corrupt and dictatorial" regime.
The military has brushed aside the Brotherhood's demands, while the new army-backed administration of interim President Adly Mansour has forged ahead with a swift timetable to amend the now suspended constitution, drafted under Morsi, and to hold parliamentary and presidential elections by early next year.
While the presidency has floated offers of reconciliation with the Brotherhood, authorities are simultaneously clamping down the group. So far, five of its top leaders have been arrested, and arrest warrants have been issued against the group's top leader and nine other Islamists.
Prosecutors today said they continue to investigate allegations that Morsi and 30 other Brotherhood leaders escaped from prison in 2011 with help from the Palestinian militant group Hamas. That jailbreak occurred amid the uprising that toppled Mubarak.
Street violence has largely ceased since Monday's deadly clashes that left more than 50 Muslim Brotherhood supporters dead and hundreds wounded after they were holding a sit-in in front of Republican Guard forces club.
The Brotherhood accuses the military of opening fire on protesters, while the army says Morsi supporters instigated the violence.
