The 92-year-old Jat leader breathed his last at 6 AM, SMS Hospital Superintendent Dr Virendra Singh told PTI here.
He was admitted to the hospital recently after he complained of swelling in his legs and stomach. He was suffering from diabetes, osteoarthritis and septicaemia.
His elder son and former Congress minister, Mahipal Maderna, who is in jail in connection with Bhanwari Devi's murder case, was given interim bail to attend to his ailing father by a court on February 12.
