Tripura Assembly Speaker Biswa Bandhu Sen, a prominent legislator and four-time Member of Legislative Assembly from Dharmanagar constituency, passed away early Thursday morning at a private hospital in Bengaluru, marking a significant loss to the state’s political landscape. He was 72 years old.
Sen breathed his last at 3:30 AM IST, concluding his four-month battle following a massive cerebral stroke he suffered in August 2025. The 11th Speaker of the Tripura Legislative Assembly, who held the prestigious office since June 21, 2018, as deputy speaker in first term and as a speaker in second term, left behind an enduring legacy of parliamentary acumen, democratic principles, and unwavering commitment to regional development.
Prime Minister Narendra Modi, Home Minister Amit Shah, and political leaders across party lines have expressed deep condolences over Sen’s demise. The Tripura government has declared three days of state mourning from December 26-28, with full state honors being accorded to the veteran legislator. His mortal remains will arrive in Agartala on December 27, with a state funeral scheduled for the same day.
POLITICAL CAREER AND ELECTORAL HISTORY
Biswa Bandhu Sen’s political journey spanned nearly two decades, characterized by consistent public service and evolving political alignments rooted in his commitment to grassroots development. Born on May 23, 1953, in Dharmanagar—a town in North Tripura district—Sen established himself as a formidable political force through four consecutive electoral victories.
Initial Congressional Phase (2008-2013)
Sen first contested the 2008 Assembly elections on the Indian National Congress ticket from Dharmanagar, defeating his primary opponent by a margin of 2,410 votes, securing 51.65 percent of the polled votes. He retained the seat in the 2013 Assembly elections with an even broader mandate, defeating his rival by 1,844 votes and securing 50.99 percent of the votes cast. During this period, Sen was recognized as a Congress party loyalist, advocating for development initiatives in the Dharmanagar region, which was administratively part of the Unakoti district at that time.
Transition to the BJP (2017-Present)
In 2017, responding to what he perceived as the need for change at the national level, Sen joined the Bharatiya Janata Party (BJP). This transition proved to be politically prescient. In the 2018 Assembly elections, Sen secured his third consecutive victory on the BJP ticket with an impressive 57.21 percent of votes, decisively defeating Congress candidate Abhijit De by 7,287 votes. His 2023 re-election on the BJP platform underscored his sustained political relevance and grassroots support, though with a narrower margin of 1,098 votes against the opposition candidate.
Legislative Leadership Roles
Following the 2018 election victory, Sen was appointed Deputy Speaker of the Tripura Legislative Assembly on June 21, 2018, a position he held until March 2, 2023. His performance in this role—characterized by impartial conduct and respect for parliamentary traditions—established him as a consensus figure capable of managing the legislature’s procedural and administrative complexities.
In March 2023, Sen was elected as the 11th Speaker of the Tripura Legislative Assembly, defeating Congress candidate Gopal Chandra Roy with a decisive vote margin of 32 to 14. His election to this constitutionally significant position reflected recognition across the political spectrum of his legislative credentials and commitment to democratic norms.
TENURE AS ASSEMBLY SPEAKER: STEWARDSHIP AND IMPACT
Biswa Bandhu Sen’s tenure as Assembly Speaker—spanning from March 2023 until his death in December 2025—was marked by a steadfast commitment to parliamentary traditions, impartial conduct of legislative business, and advocacy for the institution’s constitutional prerogatives.
Institutional Stewardship
As Speaker, Sen presided over the Assembly’s deliberations with demonstrable fairness and respect for the rights of all legislators, irrespective of party affiliation. He was instrumental in ensuring that the Assembly functioned as a forum for constructive debate and legislative scrutiny, rather than a platform for partisan confrontation. His tenure witnessed the passage of numerous bills addressing public welfare, economic development, and social security—matters that reflected the collective aspirations of Tripura’s people.
Parliamentary Advocacy
One of the defining characteristics of Sen’s speakership was his robust advocacy for parliamentary traditions and the constitutional role of legislative bodies in India’s federal structure. He consistently emphasized the Speaker’s role as a constitutional custodian, ensuring that the Assembly maintained its dignity and the legislature’s authority remained uncompromised. This principled stance resonated across political circles and contributed to his reputation as a guardian of democratic institutions.
REGIONAL DEVELOPMENT: LEGACY OF GRASSROOTS COMMITMENT
Beyond his legislative roles, Biswa Bandhu Sen is remembered for his relentless advocacy for Dharmanagar and North Tripura’s development. His political career was deeply rooted in the region’s aspirations and challenges, making regional growth a central motif of his public service.
Instrumental Role in North Tripura District Formation
One of Sen’s most significant contributions was his pivotal role in securing district status for Dharmanagar region. Long advocating for administrative bifurcation, Sen championed the creation of the North Tripura District, recognizing that the region’s geographical distance from traditional district headquarters was hindering development initiatives. This administrative reorganization—realized during his political career—has facilitated improved governance, more responsive administration, and accelerated development projects in the region.
Historic 100-Hour Hunger Strike (2012)
In 2012, Sen undertook a dramatic 100-hour hunger strike to mobilize public attention and governmental action on six priority demands for Dharmanagar’s development. These demands encompassed the establishment of educational institutions, expansion of healthcare facilities, and acceleration of infrastructure projects—all critical for the region’s socio-economic progress. This act of political resistance, undertaken at considerable personal cost, exemplified Sen’s willingness to transcend conventional political channels when addressing his constituents’ fundamental needs.
Educational and Healthcare Initiatives
Sen was instrumental in advancing the cause of higher education in Dharmanagar, advocating for university-level institutions and technical colleges that would reduce educational disparities between urban and rural areas. His efforts to establish branches of major healthcare facilities—including his initiative to bring a branch of the Kachar Cancer Hospital to the region—reflected his understanding that healthcare access is fundamental to human development.
HEALTH CRISIS AND FINAL MONTHS
Biswa Bandhu Sen’s sudden health crisis in August 2025 shocked the political establishment and his constituents alike. On August 8, 2025, while boarding a train at Agartala Railway Station en route to Dharmanagar, Sen collapsed in the toilet compartment, suffering a massive cerebral stroke.
Emergency Intervention and Treatment
Following immediate emergency response, Sen was rushed to Tripura Medical College and Hospital, where neurosurgeons performed critical brain surgery to address the hemorrhagic stroke. Despite the initial stabilization, the severity of the neurological event necessitated advanced treatment beyond state facilities. Consequently, on August 11, 2025, Sen was airlifted to Bengaluru for specialized care at a premier private healthcare facility.
Throughout his hospitalization, Chief Minister Manik Saha ensured comprehensive government support, coordinating with AIIMS New Delhi specialists who provided remote consultation. The medical team attempted various therapeutic interventions over four months, reflecting the critical importance placed on preserving the life of one of the state’s most senior political figures. However, despite extraordinary medical efforts and the unwavering support of his family, the cumulative effects of the stroke proved insurmountable.
Sen’s four-month battle with his condition—endured largely away from public view—demonstrated remarkable resilience, even as his health gradually deteriorated. His death on December 26, 2025, concluded a struggle that had tested both his physical constitution and the emotional reserves of his family and political colleagues.

The passing of Biswa Bandhu Sen elicited expressions of deep sorrow from India’s highest echelons of political leadership, reflecting recognition of his contributions to democratic governance and regional development.

The Prime Minister’s words underscored Sen’s impact beyond the legislative sphere, acknowledging his multifaceted contributions to social welfare and institutional development in Tripura.
Home Minister’s Condolences
Union Home Minister Amit Shah characterized Biswa Bandhu Sen as a “committed leader” dedicated to public service over many years, and described his death as a “grave loss to the state.” Shah’s statement reflected the central government’s recognition of Sen’s pivotal role in Tripura’s administrative and political functioning.

Chief Minister’s Statement

The ceremonial arrangements reflect the constitutional significance of his position and his stature as a senior public figure.
PERSONAL LIFE AND FAMILY
Biswa Bandhu Sen is survived by his wife, a retired government schoolteacher; one son who is a practicing physician; and one daughter. His family provided steadfast support throughout his four-month hospitalization in Bengaluru, maintaining vigil as medical teams exhausted every therapeutic option.
Beyond his legislative roles, Sen was known for his involvement in cultural and artistic pursuits. He was an accomplished theatre actor and cultural activist, demonstrating a multidimensional personality that extended beyond political governance into the realm of arts and social expression.[16]
COMPREHENSIVE LEGACY: SOCIAL WELFARE AND INSTITUTIONAL WORK
Biswa Bandhu Sen’s political career encompassed numerous initiatives beyond legislative and administrative functions, reflecting a holistic approach to public service.
Welfare of Persons with Disabilities
Sen was deeply committed to the welfare and empowerment of persons with visual impairments and other disabilities. His advocacy efforts contributed to policy initiatives and resource allocation aimed at improving educational access, employment opportunities, and social integration for disabled individuals in Tripura.
Educational Institution Development
His persistent efforts to establish educational institutions in Dharmanagar—including attempts to bring higher education infrastructure to a region historically underserved by university-level facilities—reflected his conviction that educational equity is foundational to regional development. These efforts resulted in the establishment of several colleges and the expansion of educational opportunities for thousands of students in North Tripura.
Healthcare Infrastructure Expansion
Sen’s initiative to establish a branch of the Kachar Cancer Hospital in Dharmanagar addressed a critical healthcare gap in the region. Recognizing that cancer patients from North Tripura were forced to travel extensive distances for specialized treatment, his advocacy contributed to bringing tertiary care facilities closer to his constituents.
KEY MILESTONES AND CHRONOLOGY
INSTITUTIONAL IMPACT AND PARLIAMENTARY CONTRIBUTIONS
During his 2.75-year tenure as Assembly Speaker, Biswa Bandhu Sen presided over a period of significant legislative activity. His impartial conduct earned him respect from legislators across party lines, a relatively uncommon achievement in contemporary Indian state politics characterized by increasing partisan divides.
Legislative Productivity
Sen’s speakership witnessed the passage of numerous bills addressing critical areas including public welfare, economic development, healthcare, and education. His balanced approach to admitting bills, amendments, and maintaining legislative decorum contributed to productive parliamentary sessions that addressed both government priorities and legitimate opposition concerns.
Constitutional Propriety
A defining feature of Sen’s speakership was his commitment to constitutional propriety and the Speaker’s constitutional role as an impartial custodian of parliamentary procedures. In an era when some state Speakers have been perceived as partisan functionaries, Sen’s emphasis on procedural fairness and respect for the legislature’s constitutional authority served as a corrective counter-example.
CONCLUSION: ASSESSING THE POLITICAL LEGACY
The passing of Biswa Bandhu Sen represents more than the loss of an individual legislator; it marks the departure of a political figure whose career embodied the aspirations of regional development and democratic governance in Northeast India.
Sen’s political evolution—from Congress loyalist to BJP member—reflected not opportunistic party-switching but rather a principled reassessment of which political platform could best advance his region’s interests. This flexibility, grounded in constituent service rather than rigid ideological commitment, characterized his political approach throughout his career.
His legacy encompasses several dimensions: the institutional significance of his role in forming North Tripura District, the parliamentary norms he embodied as Speaker, and the grassroots political culture he represented. For younger legislators and aspiring public servants, Sen’s example demonstrates that sustained electoral success and institutional credibility are built through consistent attention to constituent needs and unwavering commitment to democratic principles.
As Tripura mourns his passing and reflects on his contributions, the challenge ahead is ensuring that Sen’s model of responsive governance and parliamentary propriety continues to inspire the state’s political culture. The Assembly will need to select his successor carefully, ensuring continuity of the institutional standards he established and the inclusive parliamentary traditions he championed.
