Minister of State for Finance Santosh Kumar Gangwar on Saturday urged Delhi Chief Minister Arvind Kejriwal to stop degrading the demonetisation initiative of government and validate his claims. \u201cArvind Kejriwal is just trying to degrade this initiative taken by government, can he validate any of his claim,\u201d Gangwar told ANI. Gangwar said the opposition has nothing to say except criticising all of the Centre\u2019s scheme. Kejriwal on Saturday asserted that a few corporate houses were informed before hand about the radical decision to demonetize. \u201cIn the name of demonetisation, a huge scam is being played out. Before the Prime Minister Modi announced the move on Tuesday, the Bharatiya Janata Party (BJP) and its friends had been alerted before and they had stashed their cash,\u201d Kejriwal said. He said that in last three months, thousands of crores of rupees have been deposited in the bank accounts of some people and corporate houses, adding that deposition of such large sums creates suspicions.
