Digging in his heels, Finance Minister Arun Jaitley today ruled out roll back of the demonetisation decision and slammed Delhi and West Bengal Chief Ministers accusing them of spreading “unnecessary panic”.He said the move to demonetise the high value notes was “very well planned”, and added that the rush in bank branches is “significantly” coming down and 22,000 ATMs are getting recalibrated daily in order to dispense Rs 100, and new 500 and 2,000 rupee notes.
