Talking to newsmen here, Biswas said that Banerjee had not been able to come out of her mindset of a street fighter.
"Her style of work is autocratic and she does not believe in collective leadership. She does not believe in democracy," he said.
For Banerjee, there exists only the Chief Minister in the government and none else matters, Biswas remarks.
Speaking at the end of a two-day meeting of the national council of the Akhil Hind Agragami Kishan Sabha, the leader said in politics one should have patience to tolerate criticism, but her reply to Justice Katju's comment did not behove a chief minister.
"Due to the autocratic style of her functioning, the freedom of speech in Bengal is in peril," he said, accusing Banerjee of not only betraying 'Maa, Mati, Manus', but also having "kept the then Governor of West Bengal in the dark over Singur land issue".
He said the Left Front had been punished for wrong tackling of Nandigram and Singur, and felt the people of West Bengal would now teach Banerjee a lesson.
