Egypt's ousted president Mohamed Morsi has rejected the authority of the court that is due to try him next week for incitement to murder, his supporters said.
Morsi, an Islamist hailing from the Muslim Brotherhood who was Egypt's first freely elected leader, was ousted by the military on July 3 amid massive protests against his year-long rule.
He is due to stand trial with 14 others on November 4 for incitement to murder in connection with deadly clashes between his supporters and opponents outside the presidential palace in December 2012.
"No lawyers will be defending president Mohamed Morsi, neither Egyptians nor foreigners, because the president does not recognise the trial or any action and processes that result from the coup," the Anti-Coup Alliance, led by the Muslim Brotherhood, said in a statement.
The group said a team of Egyptian lawyers would be attending the trial with Morsi, but only "to observe proceedings, not to defend him."
It said its statement was prompted by false reports in pro-military media outlets saying the Muslim Brotherhood had appointed lawyers from Turkey and Qatar to represent Morsi.
The group called on international human rights activists and lawyers to attend the trial to see first hand "the trampling of justice."
The Anti-Coup Alliance has called for mass protests on the day of the trial, raising fears of further violence in the deeply polarised country.
Security forces launched a massive crackdown on Morsi's supporters in August, violently dispersing two protest camps in Cairo.
More than 1,000 people have been killed since Morsi's ouster -- mainly his supporters -- and the authorities have arrested some 2,000 Islamists, including most of the Muslim Brotherhood's leadership.
Morsi himself has been held incommunicado in military custody since his ouster.
Islamist militants have meanwhile attacked Coptic Christians and security forces, mainly in Upper Egypt and the increasingly volatile Sinai Peninsula.
