Talks over Gibraltar are still going on between Britain and Spain over Gibraltar even after the UK and the EU reached a post-Brexit trade deal a few days ago. London and Madrid are now racing against time to hammer out how the shared border will be once the Brexit transition ends on December 31. The talks are focused mostly on the free movement of thousands of people between Spain and Gibraltar.
Spain expected to get Gibraltar back despite the population not wanting that result. As such they made border movement s very low priority. I really don't understand why Spain loves people who dislike it so much.
