Earlier in the day, Congress leader Sonia Gandhi visited Lilavati Hospital, where Kadam had been undergoing treatment for renal dysfunction. He had been put on ventilator for the past few days as his condition remained serious.
Born in a lower-middle class family in Sangli district of Western Maharashtra, Kadam had a rapid rise in the fields of politics and education.
He joined the Congress and was elected to the state Assembly four times from Palus-Kadegaon constituency in western India.
Kadam also founded Bharati Vidyapeeth Deemed University, an educational empire which is spread across the state.
He held key portfolios such as cooperation and forest in the Congress-NCP government (1999 to 2014). Kadam also used to head a local cooperative sugar mill.
During his stint at MSRTC, Kadam started a scheme under which every major village in the state was connected with MSRTC bus service.
