Former Pakistan prime minister Imran Khan was transferred back to jail early on Friday, hours after being taken to a hospital for court-ordered medical checks, the government said. The Supreme Court ordered on Tuesday that Khan, Pakistan's most popular politician, be taken to the private Shifa International Hospital in the capital Islamabad within 48 hours for treatment, after his lawyers petitioned the court over concerns that his health was poor. The ex-cricket captain and his wife Bushra Bibi, who is also his spiritual guide, were both sentenced late last year to 17 years in prison. Information Minister Attaullah Tarar wrote on X that Khan was instead taken to the public hospital Pakistan Institute of Medical Sciences (PIMS) in Islamabad, blaming the "security situation" caused by Khan's supporters at the private clinic. "A team of qualified doctors, including an ophthalmologist, a cardiologist, and a physician, conducted a detailed examination of him and declared him medically fit," Tarar said. "After the completion of this entire process, he was transferred back to Adiala Jail." Tarar also said that Khan's sister, Uzma Khan, who is a medical doctor, was present during the examination.

Dozens of the 73-year-old's supporters had waited outside the hospital. The former prime minister received eye treatment at PIMS earlier this year, with his family and lawyer saying at the time that he had lost most of the vision in his right eye.
