If its no deal it will be.
The UK is a top 4 trading partner for all of the major EU economies. Upwards of €25billion of trade done by France, Spain, Italy, Netherlands. With Germany its even higher.
Then there's the fact in Spain, well, Brits account for a significant portion of the economy there, whether through tourism, or the many tens of thousands who go over to do temporary work (because we are preferable to the locals because well, contrary to the lazy Brit myth, we are anything but).
So yes, it is quite a bit deal to real people. The leaders might not show it, but then all eyes aren't non them nor are they all fighting among each other.
This is why no deal is a terrible idea, as most will agree. But also why its use should have got a better withdrawal agreement and ultimately a better trade deal.
The remainer claim that Brexit is irrelevant on the continent is as big an untruth as any Brexiteer nonsense.
