The Spanish have long argued – years before the referendum – that Gibraltar existing as a British enclave means the “disruption of national unity and territorial integrity” of Spain, and that it hurts the Spanish economy. There is just one question Theresa May and Boris Johnson need ask their Spanish counterparts: what about Ceuta? Ceuta (and another city, Melilla) are two low tax Spanish enclaves on the northern coast of Morocco. They are the EU’s only land border with Africa. Morocco want them back, but the two enclaves are autonomous, have their own governments, and return deputies and senators to the Spanish parliament in Madrid. Well, Spain, do Ceuta and Melilla disrupt the economy, national unity and territorial integrity of Morocco?
