Egypt's former Islamist president Mohamed Morsi on Tuesday attended a session in his trial for espionage, wearing for the first time the blue uniform assigned to convicts, days after he was recently  handed a 20-year sentence for inciting violence.

In previous court sessions, before Morsi was convicted of any crime, he wore white apparel worn by defendants.

Prosecutors will display evidence they claim proves Morsi and his ten co-defendants attempted to leak classified state documents to Qatar during his year in power.

Morsi is on trial in three other cases involving charges of terrorism, prison-breaking and insulting the judiciary.

His 20-year sentence is appealable.

Morsi was removed from power by Egypt's military in 2013 with the blessing of most political forces who opposed his rule after mass protests against him in July of that year.

Many top Muslim Brotherhood figures are on trial and some have received life sentences. The Brotherhood's top leader, Supreme Guide Mohamed Badie, has recently received a death sentence for inciting violence and murder. His death sentence is subject to appeal.
