I think this is actually a cunning plan - the 1M or so British migrants (AKA expats) who are currently in Spain can make their way to Gibralter (there's probably a bus) ahead of it becoming a part of Spain again, that way they get en-Spanished, and can once again enjoy things like healthcare, freedom of movement etc, and we don't have to take ~700 leathery sexpests back into the UK.
