Ousted Egyptian president Mohamed Morsi's defence filed an appeal against a death sentence and prison term for the Islamist former leader, a lawyer said on Saturday.
Morsi, who was toppled by the army in 2013, was sentenced to death in June for allegedly participating in prison breaks and violence against police, and to life in prison for espionage.
Morsi had been in prison at the start of the 2011 uprising against veteran leader Hosni Mubarak, and escaped along with thousands of others after protesters attacked police stations across the country.
"We submitted an appeal to the Court of Cassation to all prisoners sentenced, including Morsi," his lawyer Abdel Moneim Abdel Maqsud told AFP.
Hundreds of Islamists have been sentenced to death in a crackdown following Morsi's overthrow.
Most have won retrials.
Seven so far have been executed, including six defendants sentenced to death by a military court for allegedly participating in militant attacks.
