Re: So predictable !
"The WTO do not require a hard border, they require that customs are maintained across a border. That does not have to be through a physical stop at the point of crossing. Both the EU and the UK have said that they would be OK with checks occurring away from the border and through technological means, and the WTO is understood to accept such arrangements."
This doesn't exist anywhere else on the planet. No such systems have been shown to work. Even in theory it would be impossible to stop mass smuggling, never mind in practice.
