Former finance minister P Chidambaram on Tuesday took on the Modi government over its demonetisation move. He was speaking at a press conference in Nagpur. Delivering scathing comments, Chidambaram said demonetisation was the biggest scam of the year and demanded that a probe be initiated. He also said the economy was suffering as major markets in cities were closed down due to lack of cash. He also said that PM Modi could have consulted former Prime Minister Manmohan Singh as he would never have leaked the news out to anyone. Calling it a 'punishment' to the poor, Chidambaram lashed out at the move saying the effects were being seen even if one can't see the people protesting.
