G_G, maybe, but I think the Eurokings - Juncker etc - will not allow the loot go to someone else. Meaning: they will do any and everything to keep the Brits in and IF this fails, they will give em a lot of leeway.
Just imagine the amount of Polish and Hungarian etc working in the UK - if they flood back unemployed, the whole thing will implode pronto. And thats just the tip of the iceberg.
