As far as I know, the late Duke of Edinburgh made a single visit to Palma in October 1988. It will be a day which I will always remember. Queen Elizabeth and Prince Philip had embarked on the royal yacht Britannia for a private weekend holiday on Mallorca before they started an official visit to Spain on the Monday. But there was nothing low key about their visit to Mallorca. Not only did they sail into Palma aboard the royal yacht with the royal standard flying from the main mast, awaiting their arrival at the Dique del Oeste was King Juan Carlos and Queen Sofia.
