The crowd could be seen collecting garbage after the PM Modi's rally ended.

Prime Minister Narendra Modi today ended his campaign for the upcoming Haryana polls by urging voters in Millennium City Gurgaon to not just clean up the state, but also 'promise' to clean up the venue before leaving.Interestingly, most of those who attended the rally did keep their promise. The crowd could be seen collecting garbage and cleaning up the venue much after the prime minister left.There was a lot of trash left behind at Mr Modi's first rally in Karnal last Saturday, barely two days after he launched an ambitious countrywide campaign called Clean India or Swachh Bharat mission. The prime minister also nominated nine prominent Indians to spread awareness on cleanliness as part of the five-year campaign launched on the 145th birth anniversary of Mahatma Gandhi.

Perhaps Mr Modi was taking a cue from the Shiv Sena workers, who earlier this week cleaned the Mahalaxmi racecourse ground in Mumbai a day after he addressed an election rally there. Sena workers arrived with brooms and buckets and cleaned the ground, collecting leftover water bottles and campaign flags and banners.Haryana, currently governed by the BJP's arch rival, the Congress, goes to polls on October 15.
