One thing that matters enormously to UK voters is the NHS. A “battle bus” emblazoned with a claim that the NHS would receive £350m a week if the UK left the European Union was crucial to the victory of the Leave vote in the June 2016 referendum – despite the fact that this central claim was widely debunked.
Among the challenges Brexit poses to the NHS, and there are many, is that it needs to get ready to receive a group of people whose healthcare is currently being paid for by the UK in other EU countries. Many are pensioners, and large numbers of them live in Spain. There are at least 100,000 retired UK citizens in Spain, according to official figures, though local estimates suggest it could be double that, or more.
