The trouble with this subject is that, like a wheel, it keeps coming back to the same position. Then we start over.
Your statement that the EU doesn't need a trade deal is misleading. I've published the figures before somewhere on this Forum which show the amount and percentages, by country, of EU exports to the UK. For some countries they are very significant. You are talking about a UK trade imbalance with the EU to the tune of
£60+ billion a year. That's not a figure to be divided by 27, it's concentrated almost exclusively in the major players, Germany, Netherlands, France, Belgium, Spain, Italy and Ireland. It involves many thousands of jobs and a significant slice of their export market. Ireland's economy would certainly be devastated, for instance.
Annual EU exports to the UK (figures expressed in £ sterling, not €):
Germany 59 billion
Netherlands 32 billion
France 23 billion
Belgium 21 billion
Italy 16 billion
Spain 15 billion
Ireland 12 billion
The combined total of 19 of the other EU members' GDPs doesn't add up to the UK's - just to add a little perspective and feel for what will be the likely weight of their views on the matter.
The idea still mooted by some Remainers
that the EU can shrug these figures off as an irrelevance is clearly absurd. They are obviously a big deal for all concerned parties. Agreed?
Given that the UK is fully compliant with all EU trade criteria (unlike, say, Canada and Singapore with their trade deals) there's really no reason why an understanding couldn't be reached in a weekend. If people like the buffoon Junker want to "punish" the UK I suspect it's only a matter of time before somebody - well, it might just be a friendly looking granny-type from Germany - will have a quiet word in his ear. Personally, given his stumbling, inept performance so far I can't see the man finishing his time out.
What's being touted here is some sort of fanciful apocalyptic situation where absolutely all trade ceases. That would be a disaster for both sides, which is why it ain't gonna happen. Worst case would probably be reversion to WTO, which means we would be on the same playing field as a lot of the other major global traders. The same tariff barriers of course would apply to any EU goods going to the UK. That's gonna hurt everybody, as well.
I realise it's a pious thought but do you think there will ever come a time when all the doom 'n' gloom merchants will stop trawling for this stuff, accept the way the wind is blowing and for the sake of the country either zip it or get on board? No - me neither.
What it means though is that you are just doing Junker/Barnier/Tusk's work for them, divide and conquer and we could all end up the worse off for it. Food for thought?
