The Queen’s birthday was marked on Saturday with the annual Trooping the Colour in central London. More than 400 soldiers, close to 300 horses and 400 musicians took part in the event, believed to have first been performed during the reign of King Charles II. As well as Queen Elizabeth II, other members of the Royal Family in attendance included Camilla, Duchess of Cornwall, Kate, Duchess of Cambridge, Meghan, Duchess of Sussex, and Prince Harry, Duke of Sussex (see image below). ALL PICTURES: US Department of Defence photo by US Navy Petty Officer 1st Class Dominique A Pineiro (Via Flickr account of the Chairman of the Joint Chiefs of Staff/licensed under CC BY 2.0).
