The United Progressive Alliance (UPA) government’s ambitious social security programme — the proposed National Food Security scheme — could be implemented in Congress-ruled states ahead of others.

The Budget, to be tabled tomorrow in Parliament, is likely to give substantial allocation to the programme. The Centre plans to launch the programme across the country simultaneously. However, given the opposition of some non-Congress-ruled states to certain provisions of the Bill, there is a possibility that Congress-ruled states might implement it first, said sources.
