ISLAMABAD, Oct 13: National Accountability Bureau (NAB) Chairman Chaudhry Qamar Zaman has decided to reopen and pursue major corruption cases, including those against Prime Minister Nawaz Sharif, former president Asif Ali Zardari and other prominent politicians.

`The new chairman sought details of the high-profile cases and decided to go for across-the-board accountability, NAB spokesman Ramzan Sajid claimed while talking to this correspondent on Sunday.

According to him, the chairman said at a briefing that he would tolerate no delay in the processing and pursuing of such cases.

But political observers here say that the claim needs to be taken with a pinch of salt.

One of them who did not want to be identified said the NAB chairman who had been appointed after prolonged discussions between the two parties the prime minister and the leader of opposition was highly unlikely to take up this challenging task.

NAB sources said former chairman retired Admiral Fasih Bokhari had not given a goahead for pursuing the high-profile cases. `A file containing cases of more than 30 politicians was placed before the former chairman for his final approval for initiating action but he did not sign it and kept it in his own custody,` they said.

The file contained cases against the Sharif brothers, including those relating to Hudaybia Paper Mills, having assets beyond known sources of income and IttefaqFoundry loan default, they said.

Proceedings in the cases against the Sharif brothers were adjourned indefinitely by an accountability court in 2001 when the family was in exile.

After their return, NAB filed in 2007 an application for reopening the cases which was granted but proceedings were adjourned in 2010 with the court directing that the trial could commence only if an application signed by the NAB chairman was submitted.

Former interior minister Rehman Malik also referred a case against the Sharif brothers to NAB.

Presiding over a meeting and briefings, the new chairman said: `NAB officers must not only put in extra effort but also ensure transparency and an even-handed approach, irrespective of who is involved.
