DEPOSED Egyptian leader Hosni Mubarak could leave jail as early as today after a court ruling that jolted a divided nation already in turmoil seven weeks after the army toppled Islamist President Mohamed Mursi.

Convening yesterday at the Cairo jail where Mr Mubarak is held, the court upheld a petition from his lawyer demanding the release of the man who ruled Egypt for 30 years until he was overthrown during the uprisings that swept the Arab world in early 2011.

Judicial and security sources said the court had ordered Mr Mubarak's release and his lawyer, Fareed al Deeb, confirmed this as he left Tora prison after the session.

When asked when Mr Mubarak would go free, Mr al Deeb replied: "Maybe tomorrow."

Mr Mubarak, 85, was sentenced to life in prison last year for failing to prevent the killing of demonstrators but a court accepted his appeal earlier this year and ordered a retrial.

The ailing former president probably has no political future but many Egyptians would see his release as the rehabilitation of an old order that endured through six decades of military-backed rule - and even a reversal of the pro-democracy revolt that toppled him.

Meanwhile, more senior members of the pro-Mursi Muslim Brotherhood were arrested while trying to flee the country yesterday.

At least 900 people have been killed in a crackdown on the Brotherhood in the past week.
