Karachi, Sep 7 - A list of 2,500 beneficiaries of an ordinance granting immunity to Pakistani politicians and others from the corruption charges they were facing has gone missing from Sindh's interior department, Online news agency reported Monday.

However, not all is lost as the interior department had previously sent a copy of the list to the Sindh High Court.

Quoting sources, Online said a law enforcement agency had called for the list of beneficiaries of the National Reconciliation Ordinance (NRO) from the interior department a few days ago but it was found to be missing.

Sources said the list contained names of leading members of the ruling Pakistan Peoples Party (PPP), its coalition partner Muttahida Quami Movement (MQM) and the erstwhile ruling Pakistan Muslim League-Quaid (PML-Q).

Two officials of the interior department also figured in the list.

Investigations are underway to ascertain if the list is misplaced or has been deliberately taken away from the office.

Then president Pervez Musharraf had promulgated the NRO in October 2007 granting amnesty to politicians, bureaucrats and political workers accused of corruption, embezzlement, money-laundering, murder and terrorism.

It was because of the ordinance that Pakistani President Asif Ali Zardari and his late wife Benazir Bhutto could return home from exile.
