"You can discuss party matters within the party, but those who want to discuss and criticise it outside the party platform should stay outside the party," CPI(M) state secretary Biman Bose told a press conference here.
Commenting on the recent expulsion of Subhanil Chowdhury who was in charge of party's social networking platform after he openly criticised the party, Bose said, "In our party there are platforms to discuss leadership issues.
Following allegations of attacks on Left workers, he said it was decided that the leadership would rush to stand by them and give moral support in such cases.
Bose also said that the Left leadership would submit a memorandum to Chief Minister Mamata Banerjee on the attacks on CPI(M) workers in the state.
