"1: The UK is one of the EU's best internal customers. The EU loses a market of 65 million people, who will turn to other products from alternative suppliers in order to keep the weekly household bills down."

The EU does not "lose a market." Trade will continue both ways after brexit subject to tariffs even with the worst outcome. A sensible deal will minimise the tariffs. But we will still drive beamers and drink proseccco and eat Camembert.

"2: The cheaper pound? Has improved our exports and made our products more attractive world-wide, including the EU."

We are net importers, so with a weak pound we lose. And the pound has devalued by the same percentage as at Wilson's devaluation. I wonder what you were saying then.

"3. ....German industry will also be the sector hit the worst by losing us as a customer."

It will not lose us as a customer. Trading conditions will be more difficult, but we will still trade with Germany.

"4: While Backwardsman wails about the pound going through the floor...."

Gratuitous insult noted (Iains has learned a lot from you). See note above about how much the pound has fallen. It's been the main driver of recent inflation and the consequent drop in living standards to come. A weak pound is a big detriment to this country.

And you STILL haven't said anything about the catastrophic prospects for our massive service sector once the labyrinthine EU bureaucracy that doesn't currently apply kicks in.
