All the 129 seats in the six civic bodies -- Durgapur, Dhupguri, Haldia, Nalhati, Daspur and Coopers' Camp-- will witness triangular contests with the main contestants being from Congress, Trinamool Congress and CPI(M)-led Left Front.
The seats are spread over five districts -- Jalpaiguri, East Midnapore, Haldia, Birbhum and Bardhaman.
Pre-poll alliance between Congress and Trinamool Congress has failed in the municipalities, where the elections will be held.
The virtual split in the alliance was attributed to bitter relations between Congress and Trinamool Congress which jointly fought the 2011 Assembly polls.
Congress alleged that its candidates were attacked and even threatened by Trinamool Congress in some wards in a few civic bodies, which the Trinamoool Congress has countered.
CPI(M) also traded charges against Trinamool Congress about the harassment of its candidates in Haldia municipality, in particular and said free and fair poll might not be possible.
