KOLKATA: The central team sent to West Bengal to assess the Covid situation has asked state chief secretary Rajiv Sinha whether the BSF could act to ensure the team’s “safety and security in the absence of state police support”.The query came in one of the letters the central team sent to the state chief secretary on Saturday. The team has also accused the state chief secretary of “violating” the Union government order seeking cooperation for central teams visiting Covid hospitals, quarantine centres and containment zones.Though Sinha did not reply to the latest letters from the inter-ministerial central team (IMCT), Trinamool Congress responded with a salvo. “What purpose has the team served? It visited districts having no hot spots. Their real aim is to spread the political virus. They are doing it shamelessly, blatantly,” Trinamool senior and Rajya Sabha MP Derek O’Brien said. Kolkata mayor Firhad Hakim said the only purpose of the central teams’ visit was to “only serve BJP’s interests in Bengal”.The letter from Union additional secretary Apurva Chandra , who led the central team leader to south Bengal, referred to Sinha’s Friday meeting with the press. “The chief secretary has been reported as saying that the IMCT was free to go anywhere but senior state government officers could not waste their time accompanying the team. This is in violation of the ministry of home affairs’ order,” Chandra said in his letter to Sinha.
