Attacking Narendra Modi on the second anniversary of demonetisation, Congress President Rahul Gandhi on Thursday called the note ban a "cruel conspiracy" and a "scam"."Note ban was a planned and cruel conspiracy. This scam was a scheme to launder black money of the Prime Minister's cronies," Gandhi tweeted in Hindi."There was nothing innocent in this scandal. Finding any other meaning to this is an insult to the nation's intelligence," he added.
