// Yes there will be disruption, but that will apply deal or not... //
On the other hand, I won't tire of arguing the point with andy. Every single credible study I've seen shows that a No Deal exit will be significantly more disruptive than one with an organised deal. And you shouldn't even need credible studies to tell you that -- it's plain common sense that a gradual transition will be less disruptive than an abrupt one.
As to the // they need our trade more than we need theirs //, this again is based on a massive mistake. We run a trade deficit with the EU, but what matters far more is the proportional hit. If we leave without a deal and in the resultant trading mess, about half of our total volume of trade will be affected negatively. On the other hand, closer to 10% of the EU's total trading volume will be hit. Again, it should be a matter of plain common sense who will suffer the most, proportionately, in a disruptive No Deal Brexit.
This isn't the first time I've pointed it out to you, but I am pretty sure I'm still waiting for the first time for you to reply to the point. "They need us more than we need them" has been undoubtedly one of the biggest and most costly lies of the last few years.
