The civic body has deployed as many as 1,500 labourers along with four water tankers for the operation. It was noticed that right from the time when Mamata Banerjee was delivering her speech in the rally the clean-up operation had kicked off. Senior Trinamool Congress leaders present in the rally appealed to the party supporters over the microphone to vacate the place quickly to ensure that the cleaning operations started with immediate effect. With so many people from all parts of the state converging at the heart of the city, thermocol plates, food packets, tea cups, paper containers were strewn all over the venue. “We have made advance planning for the solid waste management considering the sea of people assembling in the city. Everything will be cleared by Saturday night,” a senior SWM official of the KMC said.
