King Charles III has marked his first Trooping the Colour as monarch.
The annual military parade, which marks the British sovereign's official birthday, features more than 1,400 soldiers, 200 horses and 400 musicians.
The King also became the first monarch to join the parade on horseback since his mother, Queen Elizabeth II, in 1986.
The ceremony included an extended flypast of around 70 aircraft to make up for the display at the King's coronation in May, which was scaled back due to bad weather.
