Egypt's ruling military council has vowed to hand over power to an elected president by the end of June.
The promise comes as votes are counted after Sunday's presidential run-off election, with both candidates claiming they are ahead in early results.
However, the council had earlier issued a declaration granting itself sweeping powers over legislation and the introduction of a new constitution.
Opposition groups condemned the declaration as a "coup".
