"We have geared up our party machinery for the election and the main fight would be between the TMC and the CPI-M. We would oust them from power," Roy, who arrived here on a two-day visit of organisational work in the party, said.
Without naming the BJP, Roy said that one party is claiming to be the main opposition, but the main electoral battle would only be with the TMC.
Roy also alleged that opposition parties were trying to disturb peace in West Bengal which will not be tolerated.
Regarding Presidential polls, he said that the opposition parties in the country are organised and they would announce their presidential candidate soon after the announcement by the ruling party.
