“As his legal counsel we have a right to access medical records of our client," said Sarah Bilal, of Justice Project Pakistan, a non-profit law firm.

“The judge directed them to give us the MRI scans. That’s where the spine scan will show what damage has been done to his spine.”

“If you can’t pardon somebody who’s been paralysed because of your jail’s negligence, who is going to be eligible for a pardon?"

Faisalabad prison officials insist they have shared all available documents with Basit’s counsel, but initially said they could not provide copies of the original MRI scans.

The Pakistani government has not confirmed whether it will extend Basit’s reprieve, meaning a new death warrant could be issued by the Faisalabad district court as soon as next Monday.

Its plan to execute a paralysed prisoner has been condemned by the United Nations, which says the procedure is illegal and has demanded that Basit's death sentence is commuted.

Meanwhile, Basit said in a written message passed to the Telegraph by the legal charity Reprieve that he is living in fear and hopes the Pakistani president, Mamnoon Hussain, will show him mercy.
