Mohamed Mursi has told an Egyptian court that he is still the country’s president, as his trial was put back until January 8.
Proceedings in Cairo were delayed after the deposed leader refused to wear a prison uniform.
As they got underway the judge then halted the trial amid chaotic scenes.
Mursi and other defendants interrupted the session repeatedly, and there were chants of “down with military rule”.
He and the 14 other Muslim Brotherhood members are charged with inciting the killing of protesters outside the presidential palace as opposition to Mursi’s rule spread.
Heavy security outside the court and across the country is a reminder of the military crackdown earlier this year which
saw hundreds of Mursi supporters killed and thousands more arrested.
Mursi replaced Hosni Mubarak as Egyptian president following a democratic election, but over the course of his 13 months in office he fell into conflict with a number of key institutions.
As discontent spread, the army stepped in and removed him from power in July.
Now banned, the Muslim Brotherhood has vowed to keep up street protests.
Some reports said Mursi was being moved to Cairo’s Tora prison; state media has said he will be taken to another jail in Alexandria.
Western allies have been dismayed by the military establishment’s return to the forefront of power in Cairo, prompting Washington to cut some military aid and call for free, transparent trials for all Egyptians.
The uprising that toppled Mubarak in 2011 had raised hopes that Egypt would embrace democracy and human rights and eventually enjoy economic prosperity.
Instead, the power struggle between the Brotherhood and the army-backed government has created more uncertainty.
