Prince William is reportedly "furious" with Prince Harry and Meghan Markle for "deliberately" referring to his wife as Kate instead of Catherine.

Before marrying into the Royal Family, the Princess of Wales asked her friends to call her Catherine, which is her preferred name.

However, a friend of the couple has said that the Duke of Sussex and his wife Meghan have upset the Prince of Wales by publicly calling his wife Kate, "even when they were sending her get-well-soon messages after her cancer diagnosis".
