Veteran Communist Party of India (Marxist) leader and former Member of Parliament Sudhangshu Seal passed away in Kolkata on 21 May 2026 at the age of 81. A towering figure in North Kolkata politics, Seal was widely respected for his grassroots connection and his advocacy for the unorganized labor force. His demise marks the end of an era for the Left movement in West Bengal, particularly in the urban industrial belts.
A Five-Decade Legacy in North Kolkata
Sudhangshu Seal’s political journey was deeply intertwined with the civic and social fabric of North Kolkata. He first rose to prominence through the Kolkata Municipal Corporation (KMC), representing Ward 20 as a long-standing councillor. His transition to state politics occurred in 1996 when he was elected to the West Bengal Legislative Assembly from the Jorabagan constituency, a seat he held until 2001.
The Communist Party of India (Marxist), or CPI(M), was formed in 1964 and became the dominant political force in West Bengal under the Left Front coalition from 1977 to 2011. Seal was a key organizational pillar for the party in urban Kolkata, bridging the gap between the intellectual core of the party and the working-class residents of the city’s oldest neighbourhoods. The Jorabagan constituency, which was later dissolved during the 2008 delimitation process, was known for its diverse demographic, where Seal successfully maintained a strong support base across linguistic and social divides.
The Historic 2004 Giant-Killing Feat
The pinnacle of Seal’s electoral career came during the 2004 General Elections, when he contested for the 14th Lok Sabha from the Kolkata North West constituency. In what remains one of the most discussed triangular contests in Bengal’s political history, Seal defeated the incumbent heavyweights Sudip Bandyopadhyay and Subrata Mukherjee.
At the time, Sudip Bandyopadhyay—a seasoned parliamentarian currently associated with the All India Trinamool Congress (TMC)—had contested as an Independent after falling out with the TMC leadership. Meanwhile, the official TMC candidate was Subrata Mukherjee, the then-Mayor of Kolkata. Seal’s victory in this urban stronghold was a major boost for the Left Front, which won 35 of the 42 Lok Sabha seats in West Bengal that year. The Kolkata North West seat was later merged into the Kolkata Uttar constituency following the recommendations of the Delimitation Commission in 2008.
Voice of the Unorganized Sector: CITU and Beyond
Beyond his parliamentary and legislative roles, Sudhangshu Seal was a stalwart of the trade union movement in India. He served as a senior leader of the Centre of Indian Trade Unions (CITU), the labor wing of the CPI(M) founded in 1970. His work was particularly influential in the unorganized sector, where he championed the rights of porters, vendors, and transport workers.
For several decades, Seal served as the President of the Calcutta Rickshaw Pullers’ Union, one of the oldest labor organizations in the city. He was known for his hands-on approach, often spending hours in local “Addas” (informal discussion spots) to understand the grievances of common citizens. His ability to connect with the most marginalized sections of society earned him the reputation of being a quintessential “Common Man’s Leader,” a trait that helped the CPI(M) maintain its urban presence even during periods of political decline.
Political Significance and Tributes
The passing of Sudhangshu Seal has drawn condolences from across the political spectrum, reflecting his amiable nature and the respect he commanded beyond ideological boundaries. Senior CPI(M) leaders noted that Seal’s commitment to the party’s values was unwavering, especially during the challenging years after the Left Front’s exit from power in 2011.
His life serves as a study in urban grassroots mobilization for aspirants of public administration and political science. His career demonstrates the importance of local governance (as a KMC councillor) as a foundation for higher legislative success. The state government has acknowledged his long years of service to North Kolkata, highlighting his contributions to civic infrastructure and worker welfare during his tenure in various capacities.
