So what does this mean for Brits living in the EU ?
Like my mum for example, she's British but living in the South of France. Also myself, i'm toying on the idea of one day retiring to the mountains in France. Whilst i'm currently living in the US, being a British national means i can live anywhere in the EU. Will this end ?
Not necessarily but it is possible.
It depends on any future negotiations between the individual countries or possibly the EU as a whole and the UK.
Similar to you as you are now, working and living in a foreign country.
