SPAIN/GIBRALTAR/UK (Agencies) Queen Sofía has cancelled a planned trip to London, originally scheduled for tomorrow, Friday, as part of Queen Elizabeth's Jubilee celebrations, at a luncheon at Windsor hosted by the Queen and Prince Philip. The Spanish Government deemed the visit 'inappropriate' given the present conflict between Spain and Britain over the rights of Spanish fishermen in the waters around Gibraltar. This is added to the three-day visit by Prince Edward planned for June 11. Diplomatic sources have said that the conflict was reopened after discussions between the Gibraltar Government and fishing representatives broke down last week. A third reason for the Spanish Government to advise the Royal Household to cancel Queen Sofía's visit to London, is the fact that the Royal Gibraltar Regiment is scheduled to play music in London as part of the Jubilee celebrations. Buckingham Palace was advised of the cancellation but has made no comment, the same position also being taken by the Foreign Office.
