Congress leader Adhir Ranjan Chowdhury on May 23 raised questions over CBI inquiry in Narada scam just after the assembly elections in West Bengal. He said, “There must be a Co-operative federalism, as far as the Narada scam case, this is very old case. This has been the case since 2016. Congress leaders had demanded CBI inquiry in the Calcutta High Court. His party has no problem with the central agency's probe in the case.”
