A large section of CPI(M)'s state committee leaders, in presence of the party's general secretary Sitaram Yechury and other Politburo members, said in order to fight against the "brazen attack" of TMC and communal politics of BJP, the "broadest possible unity" is needed and it cannot be achieved without Congress.
CPI(M)'s central committee had last month criticised the party's state unit for violating the 'official line' by aligning with Congress during the Assembly polls and called for rectification of the political line adopted by the state unit.
"A large number of leaders who have been vocal about an alliance with Congress have questioned the political understanding of a section of central committee leaders who have opposed the alliance," a state committee member said.
"They (the pro-alliance leaders) said that the central committee has failed to understand the extraordinary political situation in Bengal. They also said it was due to this extraordinary situation that CPI(M) in Bengal had gone for an adjustment with Congress," the leader said.
