A top Pakistani court on Friday granted bail to jailed former prime minister Nawaz Sharif who was undergoing treatment after being diagnosed with an acute immune disorder.

The 69-year-old Pakistan Muslim League-Nawaz supremo was rushed to the Services Hospital in Lahore from the National Accountability Bureau office late on Monday night after a massive drop in his platelet count.

Sharif has been under treatment at the Services Hospital since Monday night after his condition deteriorated in the NAB’s custody. He is also serving a seven-year imprisonment in the Al-Azizia corruption case.

A 10-member medical board, headed by Services Hospital Principal Ayaz Mahmood, also submitted his report to the court declaring his condition “very serious”.

However, Sharif will not be released immediately as the Islamabad High Court adjourned the hearing of his bail plea in a separate Al-Azizia steel mills case until Tuesday.The three-time premier’s lawyer Ashtar Ausaf told the court that his condition is “extremely serious” and he should be granted bail.

The NAB’s prosecutor did not challenge the defence’s plea, saying since it is a matter of serious health issue of the former premier, it does not oppose his bail.

“It is acute immune thrombocytopenic purpura, a bleeding disorder, in which the immune system destroys platelets. Since Sharif’s platelet counts are constantly reducing, we inject platelets every day but they destruct every day,” he said.

“The medical reports of the PML-N supreme leader have been sent to doctors abroad for their opinion,” a party leader said.Renowned hematologist and bone-marrow transplant expert Dr Tahir Sultan Shamsi said Sharif did not have bone cancer, but rather acute ITP which is treatable in Pakistan.

Expressing relief over the diagnosis, the doctor further said that the ailment can be cured with the right medications.Senior PML-N leader Khawaja Muhammad Asif told reporters on Thursday that going abroad for treatment if granted bail would be the discretion of Nawaz Sharif.
