The judge in Mohammed Morsi's trial has adjourned proceedings because of the behaviour of defendants.
Egyptian state television said the trial had been halted because defendants' chants were disrupting proceedings.
Security officials inside the courtroom in Cairo said the delay was caused by Mohammed Morsi insisting he would not change into the prison uniform customarily worn by defendants.
The adjournment - likely to last until later today - came after a two-hour delay in the start of the proceedings.
Morsi, who was ousted as leader in July, is charged with inciting the killing of protesters in December.
