The more I think about this - the more clever he (his advisors of course) might beAs I answered after your post George and also last night. With an extension, what was proposed could be seen as a starting point of a genuine negotiation.
As it is there are too many unknowns and lack of fine detail, that really needs to be nailed down, before any credible deal respecting consensus as defined in the GFA would get backing here or judging from the response up North from anyone else other than the DUP.
Leaving the GFA aside, there seemed to be pretty unanimous belief that the content other than that was actually unworkable.
There's a lot of work that would need to be done, but it certainly had some interesting compromises in it.
The trouble I see is that without the effective shredding of the GFA it would not get DUP support.
Of course Ireland want the full backstop - from a UK POV what a stupid move by May - it is all their Christmases at once
But has the hype and jingoism already gone so far that Ireland would choose the pain of no-deal before a more 'reasonable' (again from a UK POV) outcome?
