LONDON, ENGLAND - JUNE 25: Pride marchers wave American and rainbow flags from the top of a double decker bus with Parliament behind as the LGBT community celebrates Pride in London on June 25, 2016 in London, England. Across the city performances and speeches take place as a parade makes it way through the centre ending in Trafalgar Square. 2016 Pride in London comes just two weeks after Omar Mateen shot dead 50 people at Pulse, a gay nightclub in Orlando, Florida.
