The 2026 battle for Champdani is between incumbent Arindam Guinn of TMC, Dilip Singh of BJP and Pritam Ghosh of Congress.Champdani (constituency number 187) is an urban dominated constituency in Hooghly district, part of the Shrirampur Lok Sabha constituency. It includes Champdani Municipality, Baidyabati Municipality, parts of Serampore Municipality and Payarapur Gram Panchayat. The constituency is largely industrial in character, home to a significant working-class population historically associated with trade union politics. Sherafuli and Baidyabati towns also come under its jurisdiction.In 2021, former chairman of Baidyabati Municipality, Arindam Guinn of TMC defeated Dilip Singh of BJP by over 30,000 votes. Notably, the same Dilip Singh is once again the BJP candidate in 2026, setting up a direct contest. 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 won. Mannan later became the leader of the opposition in the state assembly. TMC recaptured the seat strongly in 2021 and Arindam Guinn is now seeking a second consecutive term against the same BJP rival.
