"Today Lakhsman Seth met Dilip Ghosh and it was finalised his 'Bharat Nirman Party' will merge with BJP in next 3-4 days. The date is yet to be finalised," a senior state BJP leader said.
Seth, a former MP and CPI(M) state committee member, was expelled from the CPI(M) for "anti-party activities" in 2014.
After expulsion from CPI(M) he had floated Bharat Nirman Party but it had failed to make any dent in the political space of the state.
The anti-land acquisition movement leaders had alleged his role caused the flare up of violence culminating in the police firing and blamed him behind atrocities on farmers who refused to part with their land.
