Talking to reporters at the CPM’s state headquarters at Alimuddin Street, where the party’s two-day state committee meeting started on Sunday, Basu said: “We understand that the opposition has entered into a grand alliance against us. We will have to gear up for that and win them back who have left us.”

He said the secretaries of district committees have been asked to submit review reports within a month.

Basu said it was not possible to meet Trinamool Congress chief Mamata Banerjee’s demand to return 400 acres of land to Singur farmers who have not received compensation. “Let Mamata say clearly whether she wants industry or not. Any sabotage

attempt at the factory will not be tolerated,” said the CPM leader.
