The ironic thing is that as a French second home owner, I'm fully aware what the consequences are. I bear no grudge against the EU for putting the UK in the same category as the rest of the world... it's not their fault that the UK made the choices it did.
I'm not sure what the Telegraph's point is... are they angry that the rules agreed to on Brexit are being applied, or that people with second homes are ignorant of the consequences of Brexit?
Or is it - hear me out here - that they just want to keep people hating the EU because, well, because... erm, foreigners?
