As for tariffs- that is a bit more complex than that. There are so many issues here and I do not have the energy tonight to even begin. Perhaps someone will oblige. Basically two main issues- re-exporting products not 100% British, be they cheese, meat products, or anything manufactured. And two- no tariffs is based on the Deal, and the Deal is based on a level playing field. Cut down on standards, or workers' rights (as alread planned, see Dan Hannan and co)- and tariffs will kick in.

Agree that loss of Erasmus can be to some extent mitigated. And I forgot No. 11- the UK also volontarily refused a Clause which would have allowed musicians to travel to EU to work, Visa free. What a dreadful shame I'd say, MusikChick.
