The request comes a day after the party's core group's meeting declared Asif a "security risk" and tasked Dar with filing a corruption complaint against the senior Pakistan Muslim League-Nawaz leader. In its letter addressed to the NAB chairman, the PTI leader alleged that Asif is part of the “gang” involved in the coverup of money laundering and financial misappropriation by former premier Nawaz Sharif. The letter states that Dar possesses irrefutable evidence against Asif, which includes foreign bank account details showing transactions worth millions. Asif used assets abroad for money laundering, the letter states. Dar in his letter requested NAB to take notice on the matter and initiate a probe into financial crimes and money laundering by Asif.
