Brexit is not about business
You artsies really are f*cking thick and out of touch with reality. That's probably the funniest thing I've read on the subject, well it would be if it wasn't so tragically stupid.
And even if you choose to ignore the practical implications of Brexit, the point that you massively missed as your head was stuck up your arse, is that the EU very much would have been listening to the governor of the B of E and all those business leaders and would have been very aware of the pressure that was putting on May and that would have impacted their attitude during negotiations.
I would have thought that was blindingly obvious to most people. Possibly not you.
