As relations remained strained between Prince Harry and his father, King Charles, and brother Prince William, he and Meghan Markle were not invited to Christmas at Sandringham, where the royal family typically spends the holiday.

One royal fan wrote: "Princess Catherine is the real deal, a timeless class act!" Another said: "The letter with words that contain warmth, emotions and magic clearly says that Kate is the princess of hearts for people. She is down to earth and deals with people on an equal level."
