The civic body of Madhya Pradesh's Indore, which has been ranked the country's cleanest city for the past six years in the Centre's Swachh Survekshan initiative, on Monday launched its 'No Thu Thu' campaign to curb spitting in public.

In the first phase, people will be advised against spitting gutkha and paan etc in public, while the second phase will see fines being imposed, Indore Mayor Pushyamitra Bhargava, who launched the campaign, said.
