Egypt's first freely elected president Morsi, who was ousted in July 2013 by the army, is already facing another case of alleged espionage and two other trials and could face the death penalty if proved guilty.
The defendants, including an Al-Jazeera employee, are charged with accessing "top secret" documents issued by highest-level state authorities to the presidency and related to national security and the Egyptian Army, and handing them to Qatar and Al-Jazeera television based in that country "in exchange for one million dollars", according to the prosecution statement.
Morsi is currently in prison over charges of killing peaceful protesters, espionage, escaping from prison during the 2011 uprising that ousted president Hosni Mubarak, insulting the judiciary and the recent charge.
He has not been sentenced in any case so far.
Since Morsi was ousted by the army in 2013 following massive protests against his rule, the Egyptian government has been cracking down on the Muslim Brotherhood and its supporters.
