"It is imperative that both the parties continue the electoral adjustment and make it stronger. WBCC will work towards strengthening the alliance with the Trinamool Congress to defeat the CPI(M) led Left Front government in the ensuing elections to the Assembly," it said.
The resolution was passed at a meeting of the extended executive committee comprising party legislators and office bearers in the presence of senior party leader and union finance minister Pranab Mukherjee.
Asked about the alliance with Trinamool Congress in the Assembly polls, Mukherjee told reporters, "There is an alliance. And, after forming the alliance we have constituted the Congress-led UPA-II government. Therefore you should wait."
When a correspondent drew his attention to a demand by a section of the Congress leaders that any alliance with TC should be on honorable terms, Mukherjee retorted, "I have no reason to explain, because when the alliance will be formed, you all will see and analyse whether it is a honourable one or not. You are big analysts."
Last week, brushing aside speculation of tension with Trinamool Congress, Mukherjee had said that the two parties would form an alliance to fight the Assembly elections.
In the last Lok Sabha elections, the seat-sharing between the two parties was largely formalised on Trinamool Congress chief Mamata Banerjee's terms with Congress getting 14 seats and Trinamool 27. One seat was left to another ally Socialist Unity Centre of India-Communist.
