The main reason the UK voted to leave the EU is because the EU morphed from a free trade agreement with the other EU members into a Super State, remote and all-powerful. An analogy would be if the US joined a free trade agreement with 20 Latin American countries- but 25 years later it had become a Super State which could override any Act of Congress and in which the US was constantly outvoted 20-1. How long do you think that the US would remain part of this outfit- in the totally improbable event that it ever joined? Secondly, all-that's right, all- EU citizens have an absolute right to migrate to the UK (or anywhere else in the EU), and the poorer countries of eastern Europe were, in effect, dumping their unemployable youth in the UK. If Turkey ever joins the EU, their 80 million people will have an automatic right to move to the UK. None of this was envisioned when Britain first joined the Common Market (as it was then) in 1973.
