His untimely demise is an irreparable loss to the people of the state. I extend my heartfelt condolences to his bereaved family members and followers. I pray to the Almighty for the eternal peace of the departed soul and for strength to his family to overcome this difficult time."

As Speaker of the Assembly, Sen discharged his responsibilities with efficiency and conducted the house proceedings with fairness and exemplary competence, the Chief Minister later told the media.

Assembly Speaker Sen, who underwent an emergency surgery at a private hospital in Agartala after he suffered an internal brain haemorrhage on August 8, was taken to Bengaluru for better medical treatment on August 11.

An official said that on the initiative of Tripura Chief Minister, two doctors from All India Institute of Medical Sciences, New Delhi, came here and they examined Sen's health condition and treatment protocols first conducted at the Tripura Medical College and then at a private hospital in Agartala.

The Assembly Speaker's son, Arijit Sen, who is also a doctor, had earlier said that they have decided to shift his father to a Bengaluru-based hospital for further medical treatment.

Arijit Sen thanked Chief Minister Manik Saha and other doctors for properly managing the initial treatment in Agartala of his 72-year-old father.

The Assembly Speaker suffered a brain haemorrhage at Agartala railway station on August 8 when he just boarded a train to go to his hometown, Dharmanagar in North Tripura district.

Sen was elected to the Tripura Legislative Assembly four times -- twice from the Dharmanagar constituency on a Congress ticket in 2008 and 2013, and later twice in 2018 and 2023 as a nominee of the ruling BJP from the same seat.
