Even as the government is pushing through Congress president Sonia Gandhi’s pet project - the National Food Security Bill - two key members of the Cabinet - Finance Minister Pranab Mukherjee and Agriculture Minister Sharad Pawar - today voiced their concern over crucial aspects related to the proposed law that aims to make food a legal entitlement. While Mukherjee’s main worry was the country’s skyrocketing subsidy Bill, Pawar’s concern revolves around whether the existing mechanism was compatible enough to implement the proposed Food Security Act.
