Finance Minister Arun Jaitley yesterday called demonetisation a "watershed moment" while former premier Manmohan Singh said it was a "reckless step", as party rivals clashed on the eve of its first anniversary to be observed today as 'anti-black money' day by the BJP and 'black day' by Congress. 

Singh and Jaitley were locked in a fresh war of words after the Congress veteran said he is repeating what he said earlier that demonetisation was an "organised loot and legalised plunder."
