The military also confirmed that polls set for September would be delayed.
"It has been decided to hold [parliamentary elections] in October or November," an official from Egypt's interim ruling military council told the Mena state news agency on Wednesday.
Many of Egypt's new political parties have called for the vote to be delayed so that they can compete against better organised and more powerful opposition groups, notably the Muslim Brotherhood.
On Tuesday, the military said it would draft guidelines for selecting the 100-member assembly that will write a new Egyptian constitution. That could make it more difficult for any Islamist-led legislature to choose the body and thereby give the charter an Islamist slant, analysts say.
