“It is imperative for UPA chairperson Sonia Gandhi and Prime Minister Dr Manmohan Singh to come clean on this and immediately ordered an enquiry by sitting Supreme Court Judge to bring the truth before the public,” said Sukhbir. He added that NDA demands a white paper on disproportionate appreciation of Vadra’s wealth during last few years. Reacting upon halted mining operations in the state, Sukhbir said that it was the “gift” of Congress-led UPA Government to the general public of country as the UPA was deliberately created scarcity of sand and gravels by artificially increasing the rates of sand-gravels. At the same time, he assured that within few months, the rates of sand and gravel would come down.
