Nariman Point - NCP leader Nawab Malik took PM Narendra Modi to task. As per Malik, PM Modi should stop his radio show 'Mann Ki Baat'. Malik said," PM Modi is not a man of words, no body believes in him. He has lost faith, Modi increased the exchange amount up to Rs 4,000 and then decreased it to Rs 2,500. Even the scheduled date of receiving ban notes in the bank i.e. 31 December has been changed to 15 December. For all these false promises and reasons he must stop doing Mann Ki Baat.
