The annual Trooping the Colour has been held in London in honour of her majesty Queen Elizabeth's 93rd birthday. The royal family assembled to witness the military parade and Royal Air Force jets perform a fly past. The event is the Duchess of Sussex's first official engagement since the birth of her son Archie. Around 1,400 military personnel joined the event, capping off a busy week for the Queen who recently entertained US President Donald Trump during his state visit.
