Crowds are set to descend on central London for Trooping the Colour today (Saturday, June 14) – and some eagle-eyed royal fans have spotted what they believe is an error

Senior working royals including Prince William, Kate Middleton, Princess Anne, Prince Edward and Queen Camilla will reportedly take part in the king's birthday parade.

The Royal family marked King Charles’ official birthday with the annual Trooping the Colour ceremony in London where the monarch was joined by Prince William, Princess Catherine and their three children.

While the cost of this year’s event has not been confirmed, it was revealed by the Ministry of Defence in 2021 that it cost them £59,662.70 that year for Trooping the Colour - a fact that was revealed after a freedom of information request.

Ahead of Saturday's festivities, King Charles III also honored a handful of celebrities and public figures, including David Beckham, Gary Oldman and Elaine Paige.
