King Charles III attended his first Trooping the Colour as monarch on Saturday. The King rode on horseback for the ceremony in keeping with the tradition his mother, Queen Elizabeth II, had kept until 1986 when she was 60. More than 1,400 soldiers, 200 horses and 400 musicians took part in the event which also featured a flypast and Buckingham Palace balcony appearance. The Trooping of the Colour has marked the official birthday of the British sovereign for more than 260 years. This year it was the Welsh Guards who held the honour of trooping their colour for the King’s Birthday Parade.
