In a series of tweets, he said, "99% notes legally exchanged! Was demonetisation a scheme designed to convert black money into white? RBI \u2018gained\u2019 Rs 16,000 crore, but \u2018lost\u2019 Rs 21,000 crore in printing new notes! The economists deserve Nobel Prize. Rs 16,000 cr out of demonetised notes of Rs 1544,000 cr did not come back to RBI. That is 1%. Shame on RBI which \u2018recommended\u2019 demonetisation." 99% notes legally exchanged!

The CPM general secretary, Sitaram Yechury also lashed out at the government and said hundreds of people died in queues trying to exchange the scrapped notes.
