Kalna (SC), Assembly Constituency No. 265, lies in Purba Bardhaman district in South Bengal, along the Bhagirathi river. Covering Kalna I and II blocks and Kalna municipality, the constituency is situated in the fertile Bhagirathi valley. Kalna town has historical significance as an ancient temple town with the celebrated complex of 108 Shiva Temples, making it a minor pilgrimage and heritage centre. The 234,000+ electors are predominantly SC communities in rural areas alongside urban middle-class and trader populations in Kalna town. Key voter concerns include river embankment maintenance, flooding, agricultural support, urban heritage conservation, weaving (tant saree) livelihoods, and healthcare and connectivity. The tant weaver community's economic vulnerability is a political mobilization point. Historically Left Front, transitioning to TMC post-2011, with BJP posing a competitive challenge since 2019. Turnout at 87.9per cent in bipolar TMC-BJP contest. In 2021, TMC's Deboprasad Bag (POLTU) won by 7,478 votes (~3.6per cent of 206,444 total votes)—a moderate, not commanding, margin. A marginal TMC seat; the relatively narrow margin makes Kalna competitive for 2026. Under Bardhaman-Purba Lok Sabha, it is a closely watched barometer of TMC-BJP competition in the Bhagirathi valley agricultural belt.
