Former Egyptian president Mohammed Mursi is set to face trial for inciting the murder of protesters.
His case has been referred by Egypts state prosecutor and relates to events in December 2012 when at least seven people were killed in fighting outside the presidential palace.
Mursi was ousted from power in early July by the military following mass protests in Cairo. Since then he has been held in a secret location.
The former president will face trial with a number of other Muslim Brotherhood members, according to state media. Mursi also faces an investigation into his escape from jail during the 2011 revolution, which removed President Hosni Mubarak from power.
The trials are another measure the interim government is taking to clamp down on the supporters of the brotherhood.
Hundreds of protesters were killed in mid-August when security forces cleared pro-Mursi camps that had been set up in Cairo in protest at the removal of Mursi from power.
The interim government is pushing forward with plans to amend Egypts constitution. Interim president Adly Mansour issued a decree on 1 September to form a 50-member committee to write the final draft of the constitution, before putting it up for referendum in two months.
The committee is said to include representatives from Islamist parties Al-Azhar and the Salafist Nour party. There will be no representation by the Muslim Brotherhood.
The draft legislation includes a proposed ban on the formation of political parties based on religion.
