Yoga also reached the UK's iconic Stonehenge, with a small group of yoga enthusiasts holding a short class as thousands converged at the neolithic site to witness the sunrise for its longest day on earth or the summer solstice. Over 4,000 people participated in a two-hour programme held at 50 centres across Singapore. The event was led by High Commissioner Vijay Thakur Singh and Singapore's Minister in The Prime Minister's Office, Grace Fu.
