"Since there are some loopholes in the proposed bill, with the possibility that the legislation will infringe upon the rights of state governments, amendments should be made to it," CPI member Prakash Reddy said.
He said the Left parties, including the CPI, CPI (M) and Forward Bloc (FB) have been staging agitations in various parts of the country since yesterday over the demand.
Reddy further said the PDS system in the country need to be streamlined and its current scope be expanded.
