Crowds have gathered for the annual Trooping the Colour parade to mark King Charles III's official birthday.

The parade set off from Buckingham Palace, with King Charles and Queen Camilla making their way in a carriage along The Mall to Horseguard's Parade.

As royal colonels, the Prince of Wales, the Princess Royal and the Duke of Edinburgh rode on horseback, while other attendees included the Princess of Wales and her three children and the Duchess of Edinburgh travelled by carriage.
