Egypt’s ousted President Mohamed Morsi is being charged with handing over national security documents to Qatar, the state prosecutor says.
Relations between Egypt and Qatar have been strained since the military ousted Mohamed Morsi in July 2013 after protests against his one-year rule.
Qatar supports the Muslim Brotherhood, the Islamist group to which he belongs.
He faces several trials for charges including espionage. He has called the court illegitimate.
Several other Muslim Brotherhood leaders, as well as hundreds of ordinary members, have already been sentenced to death.
A crackdown by the authorities over the past year has seen more than 1,400 people killed and 16,000 others detained, rights activists say.
Mohamed Morsi will be tried for having “handed over to Qatari intelligence documents linked to national security… in exchange for $1 million”, the prosecutor said in a statement quoted by AFP news agency.
He was accused of passing on the files via Doha-based TV network Al Jazeera.
When the allegations emerged in August, Al Jazeera told Reuters: “Any information Al Jazeera receives is handled with the highest standard of journalistic ethics. We do not therefore comment on sources, or pass information to governments.”
Last June, a court in Egypt sentenced three Al Jazeera English journalists to between seven and 10 years in prison after convicting them charges including of spreading false news.
The three journalists have strenuously denied the charges and plan to appeal.
The court decision was criticized by journalists and human rights groups, who have campaigned for their release.
