Durrani raised questions over the delay in formation of a medical board to examine the Pakistan Muslim League-Nawaz (PML-N) president.
Recent blood test reports of Shehbaz indicated signs of cancer returning. Shehbaz, a cancer survivor, underwent further tests, including a CT scan, at Poly Clinic last month.
In light of the reports, doctors recommended that he be kept in an open and clean space which receives sunlight and fresh air. They also proposed a larger medical board comprising cancer experts be formed to examine him.
Shehbaz is in custody of the National Accountability Bureau (NAB) since October 5 in connection to the Ashiana Iqbal Housing Scheme case.
