It is no surprise that the EU are now calling for a second referendum, in the hope that the British people 'change their views' (as the Czech Prime Minister put it today), in effect saying 'you made the wrong choice, please choose again'.
I'm still at a loss to see why the EU have trashed Theresa May's Chequers plan - it is so tipped in their favour that hard Brexiteers like Johnson, Rees-Mogg and Davis are foaming at the mouth in anger over it, and yet, ironically, it is evidently too much like having EU membership for the EU's liking, so it is toast. As such, the EU is only offering two options - hard Brexit, or total capitulation. However, they will not accept Hard Brexit either, and so the choices for the UK are total capitulation or no deal. I don't think anybody in the UK is properly prepared for either of those options - but ironically we at least know what will happen if we walk away; on the other hand, we currently don't know what the EU has in mind if the UK government were to collapse and request that Article 50 be reversed - as has been said before, one would like to think that it would simply be a case of reverting back to the previous arrangement, but there is in fact no good reason to believe that this will be the case*. So what happens in the event that the EU move the goalposts and demand that the UK makes huge concessions in return for an Article 50 reprieve? It could well be a case of 'be careful what you wish for', and hopeful Remainers may well be in for a nasty surprise.
* A commenter in the FT told me that the EU had already agreed that the UK could remain the EU on our current terms up until a deadline of March 19th 2019, however they couldn't produce a source. The closest I've seen to that was a comment by the French foreign secretary saying that this could happen, but that has been squarely contradicted by EU officials more recently. If there is to be a second referendum, the terms of our staying in need to be made clear, because I fear that the overwhelming majority of Remain voters are still unaware of the possibility of a renegotiation of our terms of membership.
