Egyptian President Mohamed Morsi will authorise the armed forces to help police keep control of street protests over his attempts to push through a new constitution, the state-run newspaper al-Ahram reported.
The cabinet approved a legal measure which would give armed forces the power of arrest in a bid to "maintain security and protect vital state institutions", according to the report.
The newspaper did not say when the legal measure would be implemented.
Rival political rallies are being held in Cairo, as Egypt's president prepares to attend 'unity talks' tomorrow.
In renouncing emergency powers he deemed essential just two weeks ago, Mohamed Morsi is trying to undo some of the damage he has inflicted.
