It's always worth taking a very hard look at what the EU is saying. Not hard for me, I knew this months before the vote was ever taken simply listening to the rhetoric coming from the EU establishment. It was hard to determine which was the largest motivator of those pre Referendum statements... Overconfidence, Arrogance or Abject Fear.
Reading that article gives you a very, very good view of how this process is going to run. With 27 countries the EU has to "defend" their principles. The framework under which negotiations will be carried out will be set long before the first meeting, no variation will be allowed, the negotiator will be hugely constrained and the European Council QMV at the end will be heavily dependent on countries who have huge benefit in sending labour to the UK, not on the relatively few countries who do massive trade surpluses with the UK. This is before the EU Parliament even gets a sniff of what has been agreed.
Tusk is absolutely right when he says
the only real alternative to a “hard Brexit” is “no Brexit”
As Brexit is going to happen, it's going to be hard and everyone needs to just get on with it and make the best of it.
