time I genuinely believe that no one in government seriously thought Leave would win hence there were absolutely no plans for that outcome.
Bear - I agree with you entirely, that possible outcome was brushed under the carpet and that was mistake no.1. Mistake no.2 was underestimating the feeling of a large proportion of the voting public.
With regard to the infamous 4 pillars and how they work going forward, I think that's for negotiation at the table with the EU powers that be and whether they are prepared to negotiate on any/all of those, that we don't know (I suspect they won't especially whilst Juncker is there). The pillars were a good idea when there were only a few countries involved, it is not workable with 27 countries, times have changed and if it is to continue to work then they need to change too, otherwise, and I have said before, I think the 'four pillars' will be its eventual undoing.
