Governor RN Ravi administered the oath of office and secrecy to Adhikari amid the 'Jai Shri Ram' slogan, drumbeats, and a sea of fluttering saffron flags.

Prime Minister Narendra Modi, Union Home Minister Amit Shah, senior BJP leaders and chief ministers of NDA-ruled states attended the grand function.

Adhikari, who won from both Bhabanipur and Nandigram constituencies, took oath first, followed by senior BJP leader and party's former state unit chief Dilip Ghosh, who was inducted into the cabinet as a minister.

BJP legislators Agnimitra Paul, Ashok Kirtania, Kshudiram Tudu and Nisith Pramanik were subsequently administered the oath as ministers.

The six-member cabinet reflects the BJP's attempt at social and regional balancing ahead of the challenges of governing a politically polarised state. Ghosh won from Kharagpur Sadar, Paul from Asansol Dakshin, Kirtania from Bangaon Uttar, Tudu from Ranibandh and Pramanik from Mathabhanga in Cooch Behar district.
