The Pakistan Tehreek-e-Insaf (PTI) leader was called in by the National Accountability Bureau (NAB) on Tuesday over the Toshakhana case on July 4.
In this context, the NAB Rawalpindi summoned the PTI chairman. In relation with the £190 million NCA scandal, the accountability watchdog also called former first lady Bushra Bibi on the same day.
The PTI leader and former first lady Bushra Bibi had previously received separate summonses from the NAB on June 26.
