Prince George, Princess Charlotte and Princess Louis all "really enjoy Trooping the Colour" so it wouldn't be surprising if William brought them along, a royal commentator has claimed.

However, it has been reported that the Princess of Wales is considering appearing on the royal balcony, "if she feels well enough".
In previous years, the future Queen has been accompanied by her husband, Prince William, and their three kids, Prince George, Princess Charlotte, and Prince Louis.
