Three of Philip's German relatives - Bernhard, the Hereditary Prince of Baden; Donatus, Prince and Landgrave of Hesse; and Prince Philipp of Hohenlohe-Langenburg - are among the attendees. Prince Philip will be laid to rest on Saturday 14 The trio are great-nephews and a cousin of Philip - with the duke making it clear he wanted his "blood" family to be included in his funeral arrangements. Prince Philipp, 51, said in a statement from the house where he and his relatives remain isolated until the weekend: "It really is an incredible honour and we are all extremely touched and privileged to be included on behalf of the wider family."
