May wants to volley "Brexit means Brexit" into the long grass.
Davis and Fox are a pair of clueless blurts who are giving it large about how the UK would be "Ok with tariffs" when the reality is that they know we'd be royally goosed with tariffs for a whole host of reasons, not least our long term attractiveness to global business looking for a European manufacturing base to feed the European market. It's nothing more than bluster to give the impression that we've actually got a negotiating position that's one of strength, when the reality is, we need access to the free market and the only way we're ever going to get it, is to retain free movement. They know, the EU knows it, we bleeding know it. The whole thing is absolute cobblers, and he's going to come back from Brussels with a bloody nose.
