"As the script progresses it is becoming increasingly clear that this has been prepared to strike bargains and indulge in corruption," party state secretary Pinarayi Vijayan told reporters here.
He was referring to the decision of the High Power Committee of UDF to make changes in the liquor policy, overruling the objections from sections in the Congress.
Vijayan said the LDF would not go back on its demand for resignation of Finance Minister K M Mani, facing a Vigilance case for graft allegations hurled at him by bar owners.
The Indian Union Muslim League (IUML) and Socialist Janata Democratic (SJD), both constituents of the ruling front, had also expressed reservation over changes in the policy at the meeting held here.
Sudheeran, who has astutely campaigned for reducing the availability of liquor for leading the state to total prohibition, had opposed dilution of the policy.
