A plan so cunning that even Baldrick would be proud of it.
There's just one question... ...how do we get this massive increase in exports to the rest of the world, and why aren't we doing it already? (Please don't say that we are being held back by the EU, my poor split sides would never heal up). Of course it's more possible that exports to the EU will fall by tens of billions and we could reach your target of 25% that way, but by that stage we would all be really stony broke and banging on the door begging to be let back in.
