Bharatiya Janata Party (BJP) national unit leader, Narsimha Rao backed the party president Amit Shah's letter to AP CM and said that 80 per cent of the Rs. 1,050 crs sent for backward areas development was not utilised. This is according to the Utility Certificates (UC), submitted by the state government, he said. Without spending the sanctioned funds, why ask for more, he questioned. If they were diverted to other schemes, then the proper UCs have not been submitted, he charged.
