Union Minister for Urban Development, Housing and Urban Poverty Alleviation, and Parliamentary Affairs, M Venkaiah Naidu has called for a three-pronged strategy to relialise the goal of Clean India which should include sustained campaign - continue the chain of nine; focus more on behavioural change - encourage voluntary public participation; and to recognise ULBs, NGOs and private sector contributing significantly to the success of the mission. The minister felt that every socially conscious citizen and public representative should be persuaded to make nine people to take up the task of campaigning for Swachh Bharat and each one of them should pass on to nine others to keep the campaign going.
