"If British ministers thought Brexit was the main impediment to signing trade deals with fast-growing developing countries, they have been thoroughly disabused."
And in a sign of things to come, under the new Horizon deal, we are paying more than we were when in the EU. In effect, we have left, rejoined - and are paying an increased fee to do so.
The analogy will be all the other rebates, discounts and vetos that we had negotiated with the EU over...
Given that Boris Johnson was the prime mover behind Vote Leave winning - why are you blaming the shitshow on May's deal not getting through? Surely if you voted for Brexit, you voted for Johnson's deal?
Not that different to the rest of the UK really - the latest survey does indicate a quite large majority (58 v 32) who think we should have stayed.
