BJP Tripura unit president Manik Saha was sworn in as the chief minister of the state on Sunday morning.
Governor S.N. Arya administered the oath to Saha, a Rajya Sabha MP, at the Raj Bhavan in Agartala.
Former chief minister Biplab Deb, whose sudden resignation on Saturday evening got Saha the top job, was present at the ceremony along with BJP MLAs and state ministers.
Union Minister Pratima Bhowmick also attended the swearing-in.
Deputy Chief Minister Jishnu Dev Varma and minister Ram Prasad Paul, who broke chairs during the BJP's legislative party meeting on Saturday protesting Saha's appointment as the chief minister, arrived at the Raj Bhavan moments after the swearing-in ended.
The opposition CPI(M) MLAs boycotted the programme, alleging “fascist-style violence” in the state under the BJP's rule.
