West Bengal Chief Minister Mamata Banerjee has said in Kolkata that the BJP-led Central government is destroying federalism. She indirectly lashed out at Narendra Modi for "making India a presidential democracy".

"One government, one leader, one party: I presume we are heading towards a presidential form of election. All other parties are being fragmented. When the Karnataka government recently fell, no one said anything," the TMC supremo, whose party is losing its base to the BJP in West Bengal, said.

She suggested that she can't be scared through investigative agencies such as CBI. "They say they will capture Bengal too. I will see how that happens. We are not scared of any agency. They will call one person today and another tomorrow. If I go to jail, I will look at it as a freedom struggle," Mamata said, indirectly referring to the arrest of P Chidambaram recently.
