Rajya Sabha MP of the Shiv Sena Priyanka Chaturvedi has reacted to CBI's latest action in the Narada sting operation. She has said that the CBI has found grounds to arrest TMC MLAs in the Narada scam but three of the "dry cleaned" and "machine washed" prime suspects are free. The Central Bureau of investigation had, earlier this morning, arrested 4 TMC ministers and leaders in relation to the Narada scam. The CBI office in Kolkata has since then been seeing frenzied activity. The larger political point here remains that after the recently concluded West Bengal elections, opposition parties have been relying on Mamata Bannerjee for the united opposition to become a fulcrum and be a force against BJP.
