One of the root causes of the Govt's Brexit difficulties is that it has overpromised.
We can, it is said, reclaim our sovereignty, with the freedom to make our own rules, and, at the same time, retain many of the advantages of EU membership. 1/14

Unless we agree to certain standards and rules (and there is scope to argue about which rules), there will be borders, and checks, and tariffs. 2/
