PAKISTAN’S former prime minister Imran Khan was found not guilty on Monday of leaking state secrets, his lawyer said.

But the popular opposition leader will remain behind bars as he serves several prison terms and awaits a slew of cases pending against him.

Mr Khan was convicted in January of treason and sentenced to 10 years over an incident, popularly known as the cipher case, in which he was accused of exposing state secrets by waving a confidential document at a protest rally.

The government has not made the document public, but it is believed to be diplomatic correspondence between the Pakistani ambassador to Washington and the Foreign Ministry in Islamabad.

The former prime minister claimed the document was proof he was being threatened and that his removal in a no-confidence vote in April 2022 was a conspiracy involving the United States and allegedly executed by the military and the government in Pakistan. 

US and Pakistani officials have denied the accusation.

Mr Khan, a former cricket star turned politician who served as prime minister from 2018 until his removal, remains a popular opposition figure.

The Islamabad High Court did not elaborate on Monday’s acquittal. Its order calls for the January judgement to be set aside, though the prosecutors can appeal the acquittal.

“He shall be released forthwith, if not incarcerated in any other case,” the order concluded.

One of Mr Khan’s lawyers, Intazar Hussain Panjutha, welcomed the ruling and said the prosecution was unable to prove their case in open court.

Though a victory, the development changes nothing for Mr Khan, who will remain behind bars. 

He has been convicted in four cases and awaits other trials, with more than 150 lawsuits filed against him since his ousting from power.

Last year, Pakistan witnessed violent demonstrations after his arrest and the government has heavily clamped down on his supporters and party ever since.
