Former premier Nawaz Sharif, jailed earlier this month over graft charges, was shifted to Islamabad’s PIMS hospital after he fell sick inside prison. Sharif and his daughter Maryam Nawaz were jailed on July 13 after Accountability Court sentenced them to 10 and seven years respectively over properties in Britain which emerged in the wake of Panama Papers revelations. Caretaker home minister for Punjab Shaukat Javed said on PTV that doctors had advised his transfer to hospital after an electrocardiogram had shown "variations". “How many days he stays in hospital depends on doctors,” Javed said. The former PM was transferred to the Pakistan Institute of Medical Sciences in Islamabad. Sharif, who claims he is being targeted by the country's powerful security establishment, is fighting for his political life after his party, PML-N, lost July 25 general election to rival PTI. His brother Shehbaz Sharif, who heads the party now, has rejected election results along with other parties who have demanded fresh elections and announced they would protest against alleged election rigging.
