Foraying into politics in 1987, Kumar became a Union minister in the Vajpayee cabinet in 1998 when he was only 38. He remained in the inner circle of the central leadership of the BJP -- be it during the heyday of Atal Bihari Vajpayee or Narendra Modi now.
He served as an important link between the central and state units of the party.
Kumar joined the BJP in 1987 and never looked back, holding the posts of state secretary, state president of the Yuva Morcha, party general secretary and national secretary.
Teaming up with state BJP chief Yeddyurappa, Kumar is among the few party leaders who can be credited for the growth of the BJP in Karnataka, bringing it to power in 2008 and making it the first saffron party government in the South.
Under Kumar's stewardship as the state party chief in 2004, the BJP had emerged as the single largest party but the JDS led by former prime minister H D Deve Gowda joined hands with the Congress to form a coalition government led by Dharam Singh.
In his capacity as Union minister, Kumar had held multiple ministries, including the civil aviation, tourism, sports, youth affairs & culture, urban development & poverty alleviation and chemicals and fertilisers.
Kumar is widely credited for implementing Neem Coated Urea and setting up of Jan Aushadhi Kendras with focus on affordable quality health care.
Incidentally, Kumar and his family were closely associated in the setting up of the Sri Shankara Cancer Hospital and Research Centre in his Lok Sabha constituency.
