An Egyptian court has overturned a death sentence on the former president Mohamed Morsi and ordered a retrial.

The democratically-elected president was deposed in a 2013 coup led by ex-army chief Abdel Fattah al-Sisi after mass protests against Morsi's rule.

Morsi was immediately arrested following the coup and has been convicted in a number of high-profile cases under the new regime. He had been convicted to death in connection with a mass jail break in 2011.

Tuesday's Court of Cassation ruling means he no longer faces execution, but he is still serving lengthy jail sentences over other charges.
