The 'problem' of Gibraltar has been a constant source of diplomatic tension between Britain and Spain for over three hundred years. Franco himself described the Rock as 'a dagger in the spine of Spain', and it was during his dictatorship that Spain's diplomatic campaign to recover Gibraltar reached its height with the closing of the frontier in 1969.
