The annual Trooping the Colour parade is one of the most important royal events on the calendar and this year it is set to be a particularly special occasion.
Not only will the historical parade on Saturday be King Charles' debut at his first birthday parade as the monarch, it will also be the first time the Princess of Wales will have her new military role.
Kate became Colonel of the Irish Guards last year, which was a position previously held by her husband Prince William, and has already this year fulfilled some of her important colonel duties, including taking part in the Irish Guards' well-known St Patrick's Day parade.
