International Yoga Day is being observed on 21 June for the second year running, and none other than Indian Prime Minister Narendra Modi led from the front in celebrating the day. The United Nations had declared this day after Modi suggested it to the 69th UN General Assembly in September 2014. He had pitched for 21 June to be reserved for the celebrations as it is the longest day of the year in the northern hemisphere. The day has since become a mass people's movement.

Modi performed yoga along with over 30,000 people in the northern Indian city of Chandigarh. To commemorate the day, he released postage stamps in yogic postures called Surya Namaskar. He also announced the introduction of two awards to be rolled out from 2017, for the best contribution to Yoga internationally, and within India. To mark International Yoga Day 2016, IBTimes UK has compiled the best images of people practising yoga around the world.
