I think there's two take-outs
The first is the cull of the Clan Cameron and the modernisers
The second is the more pertinent and that concerns the Brexit ministries of FCO (Boris) International Trade (Fox) Brexit (Davis). Clearly the UK isn't going to waltz into Brussels and expect to walk away with unfettered access to the single market without having to make compromises. At some point, the Brexiteers are inevitably going to have to retreat from their highest aspirations, as they won't be able to get a clean sweep on their shopping list without having to give a few things back. When that happens there is bound to be some kick back from the dissenters on the back benchers (if only because they've had their own noses pushed out of joint). Far better to allow the Brexiteers to make these concessions than a Remainian, as the latter is always going to be vulnerable to allegations of 'selling out'
She isn't setting them up to fail necessary, but setting them up to struggle, and in doing so, protect her. It's more of an exercise in the art of realpolitik
"While I see lives, the gashes do better upon them"
that makes a lot more sense that grasses half baked Agatha Christie plots
fair play to warbler for passing that on. Where did you read it first?
