Sarah, one former member of the Royal family, has not been invited to the ceremony at Westminster Abbey, at which her daughters, Princess Beatrice and Princess Eugenie, will be among the most prominent guests.
"She will not be attending the wedding," the Telegraph quoted a spokesman for the former wife of the Duke of York as saying.
"She never expected to be invited or to attend. She will be overseas at the time," the spokesman added. (ANI)
