Former director general of the Federal Investigation Agency (FIA) Tariq Khosa has refused to head the commission formed by the Supreme Court to probe into the “memogate” scandal. Khosa formally informed the Supreme Court that he would not be able to head the commission, leaving it for the apex court to appoint someone else in his place. According to a source, a letter was delivered to the chief justice of Pakistan in his chamber regarding the refusal of Tariq Khosa. Meanwhile, Geo News reported that former FIA DG Rafiq Haider could be assigned the task in place of Tariq Khosa. The PPP had expressed its reservations on the appointment of Tariq Khosa as the head of the commission. Questioning the formation of the commission by the Supreme Court under Khosa, former law minister Babar Awan had on Thursday said that the formation of the commission was the prerogative of the executive.
