A new trial for Egypt's ousted ex-president opened Sunday in Cairo, with prosecutors accusing him of espionage and leaking confidential information to Qatar while in office.

The hearing was swiftly adjourned and a new date set for Feb. 28 after the court ruled that the defence should consult with Mohammed Morsi and the other 10 defendants in the case. Prosecutors say the other defendants are members of Morsi's Muslim Brotherhood group, which propelled him to office in 2012 but was later barred after the army overthrew him a year later.

"I am the legitimate president … and this trial is a farce," said a defiant and sometimes smiling Morsi from the defendant's cage at the hearing, presided over by Judge Mohammed Shereen Fahmy at the Cairo Criminal Court. The other defendants denied the charges, holding up four fingers in a gesture that has come to symbolize the Brotherhood's cause.

Prosecutors allege that Morsi conspired with the other defendants to leak secret state documents, including military and security files, to Qatar, which had strongly supported Morsi's presidency and became a bitter rival to his military successors. The case hinges on allegations the defendants conspired to hand deliver documents via national airline EgyptAir.

I am the legitimate president … and this trial is a farce. - Mohammed Morsi

Morsi, overthrown in July 2013 following mass protests demanding his resignation, does not recognize the court, and insists Egypt's current leadership came to power in a coup d'etat and is thus illegitimate.

Since then the government, now led by President Abdel-Fattah el-Sissi, the former head of the army, has launched a sweeping crackdown on the Brotherhood and other political opponents.

Morsi faces three other current trials on charges that include organizing jailbreaks, conspiring with foreign powers and inciting the killing of protesters — for which he could face the death penalty. He was Egypt's first democratically elected leader, but his turbulent one-year rule left the country sharply divided.

Sissi's government has branded the Brotherhood a terrorist organization and has waged a fierce crackdown on it since Morsi's ouster.
