Deb (48) became the tenth chief minister of the north eastern state.
He joins the ranks of young chief ministers of the country along with Yogi Adityanath (Uttar Pradesh), Pema Khandu (Arunachal Pradesh) and the newly-elected Meghalaya Chief Minister Conrad Sangma.
Like Manik Srakar, the Marxist chief minister he replaced, Deb had a humble beginning.
He completed his graduation from the Udaipur College in the state in 1999 and left for Delhi soon after to join the RSS.
He served the right-wing organisation for around 16 years under the guidance of Gobinda Acharya and Krishnagopal Sharma, two prominent Sangh leaders.
Deb returned to Tripura in 2015 and assumed the charge of central Jan Sampark Pramukh of BJP, and was made the state president of the saffron party on January 6, 2016 replacing Sudhindra Dasgupta, the longest-serving chief of the party in Tripura.
His wife Niti is an officer of the State Bank of India. The couple has a son and a daughter.
"I am ready to take the responsibility. I will not run away from taking any responsibility," he had told reporters in New Delhi.
The BJP demolished the Left citadel in Tripura, where polls were held on February 18. The saffron party won two-third majority with ally IPFT and ended the 25 year-long uninterrupted rule of the CPI(M)-led rule in the north eastern state.
