Rain disaster in Kolkata could have been avoided if Bengal govt had acted on warning: Amit MalviyaKolkata: BJP IT cell chief and party’s central observer for West Bengal, Amit Malviya, on Tuesday accused the Mamata Banerjee government of “criminal negligence” over the rain-induced disaster in Kolkata. He claimed that it could have been avoided had the state acted on warnings issued by the Meteorological Department a month ago. Malviya also described the current disaster as “a direct result of the criminal negligence and breathtaking apathy” of Chief Minister Mamata Banerjee and Kolkata Mayor, Firhad Hakim. “The Alipore MET department issued a warning a month ago about incessant rainfall during Puja. This is the tragic reality of Mamata’s promise to make Kolkata like London — a hollowed-out, flooded shell where citizens pay the ultimate price for corruption.
