Deputy Director NAB Rawalpindi Abdul Majid filed an application in the Accountability Court Islamabad seeking permission to interrogate Nawaz in the case of misuse of authority in purchase of 33 high security vehicles. The court had allowed the NAB team to investigate the former PM directing the jail superintendent to cooperate in this regard. On the other hand, Chairman NAB Justice (Retd) Javed Iqbal Monday said that NAB is determined to take the mega corruption cases to logical conclusion as per law. He said that corruption is the root cause of all evils plaguing the country. He said this while chairing a meeting to review monthly performance of prosecution, operation and awareness and prevention Divisions of NAB at NAB Headquarters.  He said that the present management of NAB has developed a Monitoring and Evaluation System (MES) to monitor the performance of NAB, headquarters and all regional bureaus of NAB on regular basis in order to plug loopholes if any.

The MES system not only helped in increasing operational, prosecution and monitoring and evaluation abilities of NAB. He said the main features of this system are to register complaints, scrutinise, inquiry, investigation and other details of cases and also preserve the details about NAB cases.
