Prime Minister Narendra Modi today said the fight against corruption and black money is not a political fight. <br/>Replying to the Motion of Thanks on the President's address in the Rajya Sabha, Mr Modi said, corruption has adversely impacted the aspirations of the poor and the middle class. <br/><br/>He said, government will have to be tough on those who are cheating the system and only then the hands of the poor will be strengthened. Mr Modi emphasised the need for stronger action against the corrupt. <br/><br/>He said, several members in the House have shared their views and there was considerable discussion on demonetisation. The Prime Minister said, about 700 Maoists have surrendered in 30-40 days after demonetisation process and this number is increasing. <br/><br/>Mr Modi said, India is working to correct the wrongs that entered the society. He thanked the people for supporting government's decision of demonetisation. <br/><br/>In the midst of the reply, Congress staged a walk out from the Rajya Sabha protesting Prime Minister Modi's remarks against former Prime Minister Dr Manmohan Singh on demonetisation. <br/><br/>Reacting on the Congress walk out from the House, Prime Minister Modi asked the opposition should listen to what he has to say. Attacking the opposition, Mr Modi said if they breach decorum, they should have courage to listen to the response too.
