Leading liberal Egyptian politician Mohamed ElBaradei is to be named prime minster, presidential sources say.
The reports on Mena state news agency come three days after the army removed Islamist President Mohammed Morsi, following widespread protests.
The move in turn triggered mass unrest by supporters of Mr Morsi in which more than 30 people died on Friday.
Mr ElBaradei, a former head of the UN nuclear watchdog, leads an alliance of liberal and left-wing parties.
