Bose became the convenor of Mamata’s People’s Secular Democratic Front. The CPIML (New Democracy)’s Singur unit is headd by Paltu Sen, a trade union leader based in Uttarpara in Hooghly district who got about 100 votes when he contested the Hind Motors trade union elections in 2007. The other party is CPIML (Jana Shakti) led by Alok Mukherjee based in Birbhum. He rarely comes to Kolkata. The party has no office or any public activity but has set up a camp in Singur.

Another organisation is United Students Democratic Front which is a Naxalite faction. Mazdur Kranti Parishad is another Naxalite party with some presence in Hind Motors and some other factories in Belghoria, North 24 Parganas. Among other parties are the Indian Union of Muslim League, Janata Dal United, Samajwadi Party, Samata Dal. These parties have almost no presence in the state but each one has its own score to settle with the CPM. For example, the Samajwadi Party, ridiculed by the CPM for voting with the UPA in the trust vote, has found its platform to get back — in Singur.
