Islamabad: Pakistani Prime Minister Nawaz Sharif's recovery is on track, his daughter Maryam Nawaz has said, nearly a week after he underwent surgery. "PM's recovery on course. Was made to walk several times in the corridor during the day, and up and down a flight of stairs twice," Maryam tweeted. Since Sharif was hospitalised, Maryam has taken charge of the media management in the Sharif camp, feeding the press updates on her father's medical condition, Dawn online reported. From announcing Sharif's decision to undergo the surgery, to tweeting his first picture after the procedure, Maryam's Twitter feed has provided minute details about how much time the premier would spend inside the intensive care unit (ICU). Maryam also update the media about Sharif's plans to come back home. Sharif underwent open-heart surgery at a London hospital and was moved to an intensive care unit in a stable condition last week. He is expected to return to Pakistan before the end of Ramadan, Maryam said earlier. "Three of his arteries were blocked. It will take five or six days for the prime minister to get discharged from the hospital and we expect that he will return home in three to four weeks," she had said. Following his surgery, Sharif will be overseeing the affairs of government from London.
