In the view of next year's assembly polls, the BJP reconstituted its WB unit.
The BJP dropped Netaji Subhash Chandra Bose's grandnephew Chandra Bose who earlier opposed the party's stand on CAA & NRC.
The party also included several leaders who had switched from TMC and other parties.
BJP MP from Barrackpore and former TMC leader Arjun Singh was promoted as a vice-president of the party.
BJP's state unit chief Dilip Ghosh said that among the 11 other vice presidents are BJP MP from Bankura constituency Subhas Sarkar and Mafuja Khatun, a former CPI(M) leader.
