As we know, last year's EU referendum had a clear result: the UK should Leave the EU.
However, that referendum very clearly did not say anything about how we should go about leaving, nor about what we should do thereafter. That's all up for grabs.
So, my proposal:
We agree with our EU neighbours that on midnight on the 1st of January 2018 the UK formally leaves the EU... for 24 hours. Then we go back to business as normal, and forget all about the last nine months.
That way, Farage gets his "independence day", we have a huge party (and for £350M you can buy a lot of fireworks), everyone's all excited... and then there's a bit of a hangover but we all move on. Oh, and since just about everything shuts down for that day anyway, the damage is minimised.
No, this isn't a serious suggestion... though I'm hard pressed to think of any better outcome.
