Well it would seem countries are queuing up to do trade deals with us, deals that the uncompetitive eussr previously prohibited or made virtually impossible....
Get ourselves out of the ECHR (which didnt need brexit). , our court with our judges and laws is the supreme court not one that the eussr would eventually have incorporated into its empire as the supreme court.
We will do just fine, same as we always have done..if countries like France and Italy etc had any sense theyd get out asap and start running their own affairs...
