...he might mean all the elderly (not so so elderly) Brits in the Dordogne, Gers, Tarn, Tarn-et-Garonne, Lot, Haute-Vienne, and so on, and so on, well, the South West.
But yes, Dordogne would remain the biggest spot, in which they are the most organized too, with some British papers for British there, stuffs like that.
lol, in Haute-Vienne, in the part I use to go lately, that is close to the big and touristic lake of Vassivière, this summer I even saw a small sign on a small road, going to maybe a guest house, I don't remind correctly) 'Forbidden to British people'. And you have more and more people also ranting about how British (along with other Northern Europeans, Dutch would be the other big ones) make awfully increase prices (well, indeed, those who have a old house to sell for which most French wouldn't give much money especially since most French wouldn't 'bury themselves in the South West', those don't rant at all ^^). IIrc, there might have been some tags here and there against British/Foreigners about prices too, on some small roads...
Not to speak about all the small airports it makes live in the South West, thanks to companies like Ryanair, Easy jet, etc.
Those British seem to be a necessary evil.
