Here’s the lowdown: the EU’s single market mechanism dictates freedom of movement for labor, capital, services and goods. These are not divisible; you cannot have one without the other. Still, that’s precisely what Theresa May, again, is proposing. She basically wants to keep the UK in the single market for goods, and make other arrangements for the rest. The EU will not accept that because it could have 27 other countries coming with their own versions of single market à la carte.
So why does she come with version 826 of what she already knows will not be accepted? And why did her cabinet comply? There are a few possibilities. Perhaps May has finally understood that there is no manner of leaving the EU left to her that will not lead to utter disaster. Maybe she just wants the whole thing to stop. Or maybe Boris Johnson et al, sensing failure for May, see a chance to dethrone her and take over power. Then again, maybe they all look for a way to blame the EU for their own failures.
[ZH: Obviously the resignation of 60% of her 5-person ‘Brexit’ team is not a positive (especially David Davis’ strongly worded email), but as is always the case with Brexit discussions, the next news cycle might/will change everything again]
It’s hard to say, really. What’s obvious, through the comments of industries like Airbus and Jaguar Land Rover, is that 100,000s of jobs are at stake, along with 100s of billions of investments in Britain. Large enterprises are often branched out all through the EU, and they need to comply with EU rules; separate rules for their business with the UK would be a nightmare.
And even smaller companies, to varying degrees, face those same problems. For all you may think of the EU, it has arranged the single market strictly and successfully. There are enormous advantages for companies in that. Take those away and they will look at relocating towards the continent, where they would regain those advantages.
