There is to be a celebration at Windsor Castle on Friday to mark the Queen's Diamond Jubilee year to which King Juan Carlos and Queen Sofia of Spain were invited. The King has had to decline his invitation because of his fractured hip but the Queen was all set to attend. She is of course the great-great granddaughter of Queen Victoria and also the first cousin-once-removed to Prince Philip.
The fly in the ointment though was the planned visit of The Earl and Countess of Wessex to the disputed territory of GIbraltar in June. Because of this, Queen Sofia was first told that she could attend the function on Friday in a private capacity but has now been ordered by the Spanish Government not to attend.
Previously, King Juan Carlos and Queen Sofia declined an invitation to the wedding of Prince Charles to Lady Diana Spencer because the couple were to spend the first part of their honeymoon in Gibraltar.
I understand that the sovereignty of Gibraltar is a running sore for the Spanish government but I would have thought there were more pressing issues for them to worry about at the moment like the state of the economy.
