A day after the Left rally turned violent, leaving many people including policeman injured, Banerjee accused the Front led by the Communist Party of India-Marxist (CPI-M) of political bankruptcy.
"Those who have been rejected by people, those who follow archaic politics are trying to create tension... Is this what comrades call politics?" she told a gathering on the foundation day of the Trinamool Chhatra Parishad - her party's student wing.
"The CPI-M is politically bankrupt, its ideology is bricks, guns and killing. Forget 2016, the CPI-M will not come back to power even in 3016. They have been rejected by people everywhere," said Banerjee.
Slamming the erstwhile Left government for taking Bengal to the brink of destruction, Banerjee accused the CPI-M, Congress and the Bharatiya Janata Party (BJP) of forging a tacit understanding to create trouble.
"Calling shutdowns at the drop of a hat has become the hobby of the opposition. Protests do not mean 'goondaism'. We too protested when we were in the opposition but never resorted to violence," she said.
Banerjee also charged the Congress with politicising the lynching of a college student in West Midnapore district during a clash between two groups.
"Every death is unfortunate and sad. We should not politicise them. Some people are using tragic incidents to defame the Trinamool," she said, referring to the killing of Krishna Prasad Jana on August 8.
The Congress has been up in arms over Jana's killing, alleging the administration was trying to cover it up. The party has asked the Calcutta High Court to order a CBI probe into the killing.
