LONDON: Former prime minister Nawaz Sharif underwent a series of tests and scans ahead of medical treatment at Guy’s hospital in London on Wednesday evening.

He was accompanied by his younger brother and Pakistan Muslim League-N (PML-N) president Shahbaz Sharif and his two sons, Hasan Nawaz and Hussain Nawaz, on this occasion. They stayed for a few hours at the hospital and then left for home.

Local media has quoted family sources as saying that various appointments have been booked with haematology experts, who deal with diseases of the blood and blood-forming organs, for coming days for proper diagnosis of the illness of the patient.

Dawn newspaper quoted family sources as saying that the PML-N supremo appeared weak because of his low platelets count. They said treatment plan would be chalked out once the disease was diagnosed.

In Pakistan, the ex-premier had been diagnosed with an immune system disorder and doctors had recommended him to get treatment from abroad as his health condition was not improving.

The ex-prime minister, along Shahbaz Sharif, physician Adnan Khan and two servants, had arrived in London for medical assistance via an air ambulance on evening of Nov 19.

The air ambulance had a stopover in Doha where it refuelled and fresh medical and air crew boarded on the ambulance.

Lahore High Court had, in a verdict, waived the condition placed by the government to sign an indemnity bond before his going abroad and just made him submit an affidavit in this regard.

On Nov 19, Federal Minister for Science & Technology Fawad Hussain Chaudhry had expressed his pessimism about the three-time prime minister’s return from London after getting medical treatment.

Fawad Chaudhry had wondered if the other inmates also had the right to submit an affidavit for their medical treatment and get impunity from jail sentence.
