Champdani’s 2026 battle is between TMC incumbent Arindam Guin, BJP’s Dilip Singh, and Congress’s Pritam Ghosh.Champdani (constituency no. 187) is an urban-dominated constituency in Hooghly district, part of the Sreerampur Lok Sabha segment. It covers the Champdani municipality, Baidyabati municipality, parts of Serampore municipality, and the Payarapur gram panchayat. The constituency is largely industrial in character, home to a significant working-class population historically aligned with trade union politics. The towns of Sheoraphuli and Baidyabati also fall within its jurisdiction.In 2021, TMC’s Arindam Guin, a former chairman of Baidyabati Municipality, defeated BJP’s Dilip Singh by over 30,000 votes. Notably, the same Dilip Singh is once again the BJP nominee in 2026, setting up a direct rematch. In 2016, the seat was won by Congress’s Abdul Mannan (supported by the Left Front), who defeated a TMC candidate, making it one of the rare constituencies where the Left-Congress alliance triumphed. Mannan later became Leader of the Opposition in the state assembly. The TMC recaptured the seat emphatically in 2021, and Arindam Guin now seeks his second consecutive term against the same BJP rival.
