We're getting on for 13,000 posts and I can't recall your 'we', ever describing any positive benefit from secession. That is why 'remainers' like me have repeatedly asked for 'leavers' to furnish that information.The problem BREXIT has is that everything we see as a potential benefit is met on here with a defeatist attitude.
There has been plenty of aspirational guff, interspersed by nonsensical fantasy about 'taking back control, regaining lost sovereignty??......and arranging our own trade deals with countries twice as far away as France and Iberia, essentially the breadbasket of Europe.
Frankly, I really can't see what the UK has to gain from this stupidity but I can imagine a whole load of things we will lose, not to mention the fact that we will be a laughing-stock in the eyes of other forward-looking nations.
We still haven't invoked the A50 provisions but so much stock has been placed on our forthcoming negotiations, the public might conceivably believe that we have some tools at our disposal with which to frighten some or all of the other other 27 sovereign nation states. That, of course, is a complete nonsense and is simply bluff and bravado on the part of the tory government and their media wing. In effect, we will be turning up at a gunfight armed with a knife!
You and your ilk have had 8 months to construct and develop the case you make called, 'potential benefits'. In that, you have failed miserably.
