The decision was taken at an emergency meeting of the state unit here tonight, as majority of the members were against the party warming up to the BJP, NCP state president Uzavoor Vijayan told reporters.
He said the state unit decided to ask the leadership to 'reconsider' the decision.
A resolution in this regard was also moved at the meeting which was held on "a positive" note, he said, adding "There was no ill-feeling". The state unit executive will meet next week, he said.
Thomas Chandy, MLA, had earlier said that the state unit cannot take a stand contrary to the party's decision and those who do not want to toe the party line, can leave.
Vijayan had earlier opined that he would rather quit if the party decides to support BJP in Maharashtra.
CPI(M) veteran, V S Achuthanandan, also resented the NCP's decision and said a party which took a stand helpful to the BJP would not have a place in the LDF.
