Safdar and Finance Minister Ishaq Dar to interrogate them in its Lahore office in connection with their offshore properties revealed by the Panama Papers case. <br/><br/>The watchdog, irked over the Sharif family's non-cooperation, is considering writing to the interior ministry to place their names on the Exist Control List, stopping them from leaving the country. <br/><br/>A senior NAB official told PTI that Sharif, his sons, daughter, son-in-law and the finance minister were summoned to appear before the NAB but none of them turned up. He said Sharif and his two sons failed to appear before the NAB for the third consecutive time while Maryam and Dar for the second and first time. <br/><br/>The official further said the NAB would write to interior ministry to put Sharif and his family on Exist Control List if they continued to evade the investigation.<br/><br/>On July 28, a five-member Supreme Court bench disqualified Nawaz Sharif from continuing in his office for possessing a work permit at the firm of his son in the UAE.
