The NAB Karachi recommended a reference investigation Shahid Khaqan Abbasi, ex-minster of petroleum & natural resources, for appointing Shaikh Imran ul Haq as MD Pakistan State Oil (PSO) by violating the rules and procedures set by Federal Government for the appointments of CEOs in Public Sector Enterprises. The investigation revealed that Imran ul Haq was appointed as MD PSO due to having personal affiliation with minister without ensuring his academic and professional credentials. The investigation further revealed that Sheikh Imran ul Haq developed personal relations with the petroleum minister during the establishment of LNG terminal in the year 2013 to 2015 and thus his illegal appointment caused loss amounting to Rs138.93 to the national exchequer.
