Kolkata: West Bengal Chief Minister Mamata Banerjee on Tuesday denounced the BJP for spreading the 'poison of communalism' in the state and said her Trinamool Congress will take on the 'unethical alliance' of the BJP, Congress and CPI-M in the 2016 assembly elections.

“I tell the Congress, the BJP and the CPI-M that they do not have any relevance in Bengal. They do not have any principles. BJP-Congress-CPI-M… you are shame, shame," she told hundreds of thousands of supporters.
