I have been surprised to see quite a few post on this and other forums where Brits are still talking about moving to France (or any other EU country) as if nothing has changed. I've also been surprised to see people responding to them as if they also believe nothing has changed and giving them reassurances like, 'don't worry, if you are established in country before the exit date, you will be fine'. I'd like to know where they are getting this apparent knowledge from.
The politicians in the UK and in the EU have already started back-pedaling on assurances even to those who are ALREADY living in one or the other. To suggest that if someone moves between now and the official exit date, they will be OK, becomes even more of a stretch in imagination.
