A Cairo court is to hold a “secret session” in the retrial of former President Hosni Mubarak, his two sons Alaa and Gamal, and his former top aides on Saturday.
Mubarak is in court for alleged incitement to kill protesters, and is to also stand trial this month on embezzlement charges, along with former Interior Minister Habib al-Adly and fugitive businessman Hussein Salem.
The court is to hear witness testimonies related to charges of incitement to murder and selling gas to Israel at artificially low prices.
Mubarak, 85, has remained in a military hospital in Cairo since he was freed from prison in August after the maximum pre-trial detention period expired.
He had been convicted of involvement in the murder of protesters during the 2011 uprising that toppled him, but a court ordered a retrial last year on technical grounds.
The latest charges brought against Mubarak and his two sons  involve their alleged embezzlement of 125 million Egyptian pounds ($18m) earmarked for presidential palaces.
Alaa and Gamal are already on trial with their father in the murder and corruption case, along with seven of Mubarak’s former security commanders.
Public attention has largely shifted away from Mubarak’s case, with his successor Mohammad Mursi also on trial on similar murder charges.
Mursi, elected in June 2012, was overthrown by the military almost a year later following mass protests demanding the Islamist’s resignation.
Since then Mursi’s Muslim Brotherhood, long opposed to Mubarak, has been accused of some of the worst violence during the 18-day uprising in early 2011 that overthrew Mubarak.
