The only members of the Mountbatten family to attend the wedding were the Countess Mountbatten of Burma, her son and daughter-in-law, Lord and Lady Brabourne, and her sister, Lady Pamela Hicks. Lord Brabourne, is Prince William's godfather. None of the other of Lady Mountbatten's children nor the children of Lady Pamela Hicks were invited to the wedding. Lord and Lady Brabourne are estranged, and did not sit together.

But invitations were not sent to Alexandra's brother, Prince Michael of Kent and his family.
