Former Union minister and ex-BJP leader Jaswant Singh is in coma for the 12th day on Tuesday, doctors said.
A statement from the Army Hospital (Research and Referral) said Jaswant Singh was still in coma and on ventilator support.
"Heart rhythm and BP are normal without medication," it reads.
The statement added that he has no fever.
"Follow-up CT scan done yesterday (Monday) shows some improvement from previous scan," the statement said.
The 76-year-old leader was admitted to the hospital August 8 in a critical condition with a head injury.
He was brought to the hospital by his family after they found him lying on the floor of his house in an unconscious state.
