Former Union Minister Jaswant Singh continues to be in a "very critical" condition at the Intensive Care Unit of the Army Research and Referral Hospital in Delhi, the Defence ministry has said. He is on life support system and is being monitored round the clock by a team of neurosurgeons.
Mr Singh, a former defence minister, was brought to the hospital at around 1 am on Friday "with an injury to his head," according to a statement by the ministry.
Examination at the hospital showed him to be in coma, it said.
The senior politician was found unconscious at his home in the capital and was rushed by his family to the hospital, where he was operated upon.
Senior BJP leader LK Advani and former party president Rajnath Singh visited the hospital on Friday.
Prime Minister Narendra Modi spoke to Mr Singh's family and prayed for his "speedy recovery," the Prime Minister's Office said.
The 76-year-old leader was expelled from the BJP earlier this year after he decided to contest the general elections from his home district Barmer in Rajasthan as an Independent when the party fielded someone else. The former Armyman lost the election.
Mr Singh held the important finance, defence and external affairs portfolios in previous BJP-led governments at the Centre.
