We are told that there would be a threat to the UK economy. We have just had the curious spectacle of HM Treasury insisting on the rewriting of a G20 Communique to include a reference to the potential “shock” from Brexit – surely the first time any country has used an international forum actively to talk up threats to its own economic prospects.

The agents of Project Fear – and they seem to be everywhere – have warned us that leaving the EU would jeopardise police, judicial and intelligence cooperation. We have even been told that the EU has been responsible, over the last 70 years, for “keeping the peace in Europe”. In every case the message is that Brexit is simply too scary; and the reality is that these threats are so wildly exaggerated as to be nonsense.

Indeed I am ever more convinced that the real risk is to sit back and do nothing, to remain inertly and complacently in an unreformed EU that is hell-bent on a federal project over which we have no control.

Take the so-called economic risks. Remember when you weigh them up that the people now issuing the blood-curdling warnings against Brexit are often the very same (as the former governor of the Bank of England, Mervyn King, just pointed out) as the people who prophesied disaster if Britain failed to join the euro. In fact, the opposite turned out to be true. It was the euro that proved to be a nightmare, an economic doomsday machine that is still causing low growth, high unemployment and real misery in some European countries.
