King Charles rides on horseback at Trooping the Colour

The royals were out in force today as they celebrated the King’s first birthday parade, known as Trooping the Colour.

King Charles and Queen Camilla were joined by the the Prince and Princess of Wales, the Princess Royal, and the Duke and Duchess of Edinburgh at the spectacular event in central London.

It was a milestone moment for Charles as he marked his first official birthday parade of his reign, since his accession to the throne last September.

It was also the first time a monarch has ridden on horseback since the late Queen Elizabeth II rode on her beloved horse, Burmese, in 1986.

The King was joined in the parade by the Princess Royal, who is the Senior Colonel of the Household Division, as well as the Prince of Wales, and for the first time, the Duke of Edinburgh.
