TOPSHOT-BRITAIN-ROYAL-TROOPING

TOPSHOT - Coloured smoke trails hang in the air, backdropped by The Shard skyscraper (R), and One Canada Sqaure in the Canary Wharf district of east London (2L), after members of the British Royal Air Force Aerobatic Team, the Red Arrows, flew in formation during the Queen's Birthday Parade, 'Trooping the Colour', in London on June 17, 2017. The ceremony of Trooping the Colour is believed to have first been performed during the reign of King Charles II. In 1748, it was decided that the parade would be used to mark the official birthday of the Sovereign. More than 600 guardsmen and cavalry make up the parade, a celebration of the Sovereign's official birthday, although the Queen's actual birthday is on 21 April. / AFP PHOTO / Tolga AKMEN (Photo credit should read TOLGA AKMEN/AFP via Getty Images)
