The UK is acknowledged to be the country in the EU with the highest number of its citizens living abroad. No one knows exactly how many UK citizens have taken advantage of free movement, but estimates are that there are more or less the same number as EU citizens in the UK (about two million.)

A lot of us work and take advantage of public health systems and social benefits in our adopted countries. There are some 800,000 retired UK citizens in Spain alone, who are free to use the Spanish health system (and therefore don’t take up valuable NHS beds).
