Re: So predictable !
And even if there IS a hard border -- ever driven across the EU-Swiss border? They don't quite have a sign saying "please don't rev your engines, you'll wake the customs officer" but it's pretty close."
The WTO requires customs arrangements. It's either hard border, an FTA, or magic.
Switzerland has an FTA, in fact thousands of bilateral agreements, with the EU. When the UK leaves the EU, at least right now, it will have none.
Please don't mislead with this stuff. It's serious. Max fac is magical thinking. If there is no border between France and RoI, RoI and NI, and NI and GB, there is no border between France and GB.
