Imran Khan, a former cricketer, said Shaukat Khanum Hospital Chief Medical Officer Dr Asim Yousaf had recommended conducting Bushra Bibi's tests at Shifa International Hospital in Islamabad.

He alleged that jail authorities were adamant about conducting the tests at the Pakistan Institute of Medical Sciences (PIMS) Hospital, The Express Tribune reported.

Reports said during the hearing, the judge asked Imran Khan to avoid holding press conferences while in custody. In response, the former prime minister contended that he engages with journalists regularly as his statements are misquoted.
