Arun Jaitley, who was confined to a ‘controlled environment’ at home, was shifted to AIIMS and will undergo surgery on Saturday, people privy of the development said. Jaitley, however, had not elaborated on the ailment, but said he was “currently working from controlled environment at home…” Jaitley had in September 2014 undergone a bariatric surgery to treat weight gain that he suffered because of a long-standing diabetic condition. That surgery was first performed at Max Hospital, but he had to be later shifted to AIIMS because of complications. He had a heart surgery several years ago.
