(June 2018) (Learn how and when to remove this template message) </Td> </Tr> <P> Trooping the Colour is a ceremony performed by regiments of the British and Commonwealth armies . It has been a tradition of British infantry regiments since the 17th century, although the roots go back much earlier . On battlefields, a regiment's colours, or flags, were used as rallying points . Consequently, regiments would have their ensigns slowly march with their colours between the soldiers' ranks to enable soldiers to recognise their regiments' colours . </P> <P> Since 1748, Trooping the Colour has also marked the official birthday of the British sovereign . It is held in London annually on a Saturday in June on Horse Guards Parade by St. James's Park, and coincides with the publication of the Birthday Honours List . Among the audience are the Royal Family, invited guests, ticket holders and the general public . The ceremony is broadcast live by the BBC within the UK and is also shown in Germany and Belgium, and since 2018, has been streamed online to viewers all over the world, via the Time magazine YouTube channel and the Facebook page of the British newspaper The Telegraph, with the Associated Press providing live video coverage of the event . </P> <P> The Queen travels down the Mall from Buckingham Palace in a royal procession with a sovereign's escort of Household Cavalry (mounted troops or horse guards). After receiving a royal salute, she inspects her troops of the Household Division, both foot guards and horse guards, and the King's Troop, Royal Horse Artillery . Each year, one of the foot - guards regiments is selected to troop its colour through the ranks of guards . Then the entire Household Division assembly conducts a march past the Queen, who receives a salute from the saluting base . Parading with its guns, the King's Troop takes precedence as the mounted troops perform a walk - march and trot - past . </P>
