Assam Governor Laxman Prasad Acharya administered the oath of office to the four new ministers - Prasanta Phookan, Kaushik Rai, Krishnendu Paul, and Rupesh Goala at the Srimanta Sankardeva Kalakshetra here.

The chief minister and members of his cabinet were present on the occasion.

''Congratulations to all my colleagues who have taken oath today. Looking forward to working with them to fulfil Adarniya Shri @narendramodi ji's vision of a Viksit Assam'', the chief minister posted on X.

Phukan is a four-time MLA from Dibrugarh, Paul a two-time MLA from Patharkandi while Rai and Goala are first-time MLAs from Lakhipur and Doom Dooma respectively.

Phukan and Goala represent the Upper Assam tea districts of Dibruagah and Tinsukia respectively while Paul and Rai are from the two Barak Valley districts of Sribhumi (formerly Karimganj) and Cachar.

Sarma now heads a 19-member council of ministers.

Tea Welfare and Labour minister Sanjay Kishan, who represents the Tinsukia constituency, resigned from office on Thursday, to pave the way for Goala with both representing the tea tribe community.

Kishan has since been appointed as the Chairman of the Assam Food and Civil Supplies department.

All the new ministers thanked the chief minister for including them in his ministry.

They also pledged to serve the people and work for the development of the state.

The ministers are yet to be allocated their portfolios with the chief minister likely to reshuffle and redistribute the departments among the 19 ministers by Saturday evening.

The newly sworn-in ministers will attend their first cabinet meeting later tonight.

From Barak Valley, 50-year-old first-time MLA Kaushik Rai and his party colleague 51-year-old Krishnendu Paul have become ministers.
