The UK and Spain are negotiating over the future of Gibralter, which the Britain won from Spain in the early 18th Century, and Spain has wanted back ever since.
Trouble is, nobody’s consulting the residents there. Spain’s foreign minister, for one, thinks they have no say in the matter. “Negotiations between two sovereign states cannot be subsumed to the will of 30,000 Gibraltarians. The opinion of 30,000 people will not dictate the will of two sovereign states,” says Spain’s Foreign Minister. Which is explained by (and explains) the fact that almost none of those 30,000 want to see sovereignty change.
(It’s also worth noting that, while it insists on sovereignty over Gibralter, Spain has made it clear it has no intention of letting loose of the two enclaves it still holds on the coast of North Africa, which are claimed by Morocco.)
