Of course, asking for something that's not on offer is not an answer to the question. He knows as well as I do—someone as well-informed and sophisticated as the finance Secretary must know—that the European Commission could never actually grant to the United Kingdom the kind of deviations from EU regulations on free movement that the Labour Party has been talking about. In fact, this is called 'cakeism' by the European Commission—having your cake and eating it. A source close to Guy Verhofstadt, the lead negotiator of the European Parliament on these issues, now says that 

'Labour are as bad as the Tories, selling a unicorn to paste over their internal divisions.'

Is it not clear that Labour policy now is that we'll be a rule taker on goods and European court rulings? That means not taking back control of our laws. Belief in full alignment means no free trade deals with the rest of the world, which means we don't take back control of our trade policy, and a compromise on free movement means that we don't take back control of our borders. This will all be at a price, as well; just like Norway, we'll be obliged to pay into the European budget, which means not taking back control of our money.
