Egypt’s Court of Cassation on Wednesday annulled the conviction of Mubarak-era prime minister Ahmed Nazif on charges of corruption, ordering a retrial.
Nazif was convicted in 2012 of graft and profiteering and sentenced to three years in prison; in July of this year a criminal court examining his appeal issued a new sentence of five years.
The former prime minister will face a retrial beginning on 3 February.
Nazif served as prime minister from 2004 until former president Hosni Mubarak replaced him during the popular revolution in January 2011.
He was imprisoned after Mubarak's ouster and released in June 2013 because he had spent the maximum allowed period in pre-trial detention for corruption charges.
Earlier this year, Nazif was acquitted in another graft case in which he and former interior minister Habib El-Adly had been sentenced to one year and five years in jail respectively over charges of illegal profiting and squandering public funds.
Many other Mubarak-era figures have been cleared of corruption charges in recent months.
