Industry won’t invest during the two-year interregnum, or during the multi-year hiatus after that. And all the while other European countries will lure our juiciest businesses— pharma, finance, creative industries, aerospace, cars and so forth — to their shores.
After explaining that a two-year transition won’t work, companies then need to show why the government’s policies mean that the eventual trading arrangements we get with the world will be far inferior to what we now have.
This is because the prime minister has decided to pull us out of both the EU’s single market and its customs union.
The first decision, combined with May’s plan to stop free movement of people, means the best free trade deal we can expect with the EU is something like what it already has with Canada.
We wouldn’t have tariffs. But, otherwise, the deal wouldn’t be a lot better than relying on the WTO. It would, for a start, do little for services that account for 80% of our economy.
Meanwhile, pulling out of the customs union will lead to border checks, gumming up manufacturers’ supply chains which criss-cross Europe. The official reason the prime minister wants to inflict this wound on the economy is so we are free to cut lots of other deals with the rest of the world.
But that’s nonsense too. Quitting the EU means we’ll immediately lose deals it already has with over 50 countries including Switzerland, South Korea and Canada.
We can, of course, plead with Donald Trump to give us a trade deal. Maybe the prime minister will arm-twist Prince Harry to invite the American president to his wedding to curry favour. But even if the US decides to do a deal, its economic clout means it can largely dictate the terms. The same goes for China.
Business needs to explain why this means that, even when we finally sort out our trading arrangements with the world, we won’t be as attractive a place to invest in, and we’ll be fighting the global war for talent with one hand tied behind our back.
As a result, we’ll be stuck in the slow lane of the world economy for as far as the eye can see.
If industry sets out these points clearly and unemotionally, we could end up with a less destructive Brexit than the one the Tories are hell-bent on. And if the voters listen, there’s even a chance that they’ll decide they don’t want Brexit at all and put pressure on politicians to stop the whole mad escapade.
