A trade deal involves, and is often conditional on, clauses that involve the free movement of people between the countries negotiating the deal.
I don’t think that everyone who voted Leave understands this, and that for every European worker being shown out the door, when freedom of movement ends, they will be replaced by immigrants from other parts of the world, as a result of those countries insisting on more entry visas being issued to their citizens in return for a trade deal.
I think some of the nastier types will be apoplectic with rage when they realise that we will be swapping immigrants, with the same colour skin as us, for immigrants whose skin is a different shade.
Should make for some interesting news interviews and, who knows, maybe the penny will finally drop that they have been conned by the people who told them that we were taking back control.
