The United Nations will soon declare June 21 as World Yoga Day following a proposal by Prime Minister Narendra Modi, says External Affairs Minister Sushma Swaraj. "Three months ago, Prime Minister Narendra Modi had appealed to the world community that India's yoga should be celebrated as World Yoga Day. I am happy to inform you that we have received support of 170 nations and very shortly the United Nations will declare June 21 as the World Yoga Day," Swaraj said at a function in the presence of yoga guru Ramdev.
