Goregaon - “Prime minister Narendra Modi had taken a decision of demonetization to end black money menace, to stop corruption and to check the bogus currency in the market. None of these objective have been achieved and corruption is still going on,” said former chief minister Prithviraj Chavan. The economy of the country is going to face a tough time in the coming time. Modi has also understood that his decision has gone wrong, said NCP leader and former finance minister Jayant Patil. Both these leaders were addressing a lecture series on demonetization organised by the Parvati Shankarrao Chavan Trust and the Goregaon Vikash Manch.
