Misleading title. Brexit will not be renegotiated, it’s over and done with. The relation between the UK and the EU will always be an evolving matter (like the relation of the EU and any other country including its members), bit Brexit is done, the UK is out and that’s the new premise of any discussion and evolution of the relation.

I upvoted because this message still didn’t reach everyone, but I guess it’s just that people are in denial… like, isn’t this obvious? And weren’t there already dozens of studies proving it?
