However, NAB Judge Bashir Ahmed suo motu reopened five old cases. The cases are related to favouratism, misuse of power by Zardari during his party's previous government of his slain spouse, then prime minister Benazir Bhutto, and allegedly receiving kickbacks by awarding contracts. The PPP has criticised revival of the cases but said the former president would defend himself in court. The party's lawyer, Farooq Naek, said that none of the corruption charges has been proved against Zardari and these cases were registered for political motives.
