Economics may well be a pseudo science.
I havent mentioned economics, haveI?
Lets stick to simple facts.
Leave with no deal: means losing all trade agreements, which will be damaging.
Leave with a deal: cant be done by 31st Oct, Boris has set red lines which the EU wont agree with.
You can carve it up however you like, one way or another we will continue to trade under the existing EU trade agreements.
And that means regulatory alignment -so no US trade deal. Or US trade deal and regulatory divergence, which means loss of all 759 trade agreements and border controls.....which given the amount of trade with the EU wont be beneficial to our economy.
As weve been told all along, the closer the alignment we have to the EU, the less damage.
Im sorry if this is boring but I need to emphasisi: it is all to do with trade agreements and regulatory standards.
