KARACHI: Pakistan Peoples Party (PPP) chairman Bilawal Bhutto Zardari Thursday said that he was appalled at hearing of the "callous and inhumane" treatment of imprisoned former prime minister Nawaz Sharif by the government. "His illness should be treated seriously, be provided with proper medical care and treated with respect," Bilawal said in his tweet. The statement by the PPP chairman comes a day after Nawaz told family members visiting him at the Kot Lakhpat jail that he had not begged for treatment, nor would he ask for it. The former prime minister has been imprisoned at Kot Lakhpat jail since December 2018 following his conviction in a corruption reference in line with the Supreme Court’s July 2017 verdict. Nawaz's mother, his brother Shehbaz Sharif and daughter Maryam Nawaz met the former premier on Wednesday to convince him to be shifted to hospital. "The insulting behaviour of the government is not acceptable," he said, adding he was being taken to one hospital from another. The former premier lamented that his treatment was not initiated despite reports from five medical boards. "The government has not yet provided any treatment facility, [I am] only being troubled," he said.
