Brexit. UK-EU talks. Let's try to explain why we're in such a state, of increased risk of no deal, moving away from the fish and playing fields which are the detail but not the answer, to differing philosophies and divorce parallels that might just help... 1/

First, with apologies to those concerned, we need to go beyond those saying this is the inevitable path to deal / no-deal. Half of them will be right and I'll definitely be wrong (don't worry, I'm hedged in wine bets), but it wasn't inevitable, typical, or necessary. 2/

I'll also ignore the content of any deal, which has been clear for months, the UK compromises on level playing field, the EU on fish. Something so obvious really isn't the fundamental issue. Could, as some not noted for their perspicacity have said, be done in an afternoon. 3/

Some truth in the idea that flounces and playing the tough cop are a part of trade negotiations. But equally as we're in about the 5th pass of these, I think it has ceased to be helpful. Either side could already have cut the deal having shown their toughness. 4/

Some fundamentals then, that we've forgotten. First, the trade deal that will lead to much less free trade than before. The incentive structures, the ability to create a win-win, are inevitably going to be different to a normal deal. 5/
