Finance Minister Arun Jaitley today lashed out at critics of demonetisation, dubbing them "prophets of doom" hours after former prime minister Manmohan Singh's scathing takedown of the move he said had left scars and wounds that were getting more visible with time. Attacked by the opposition on the second anniversary of the notes ban, Mr Jaitley said India managed "respectable growth" despite global stress because of the "courage" of the prime minister.
