Yet, if you belong to the Single Market then you are obliged to accept its rules and regulations for the whole of your economy. About 40pc-45pc of our exports go to the EU. But, for simplicity, let’s assume the figure is 50pc. Since we export about 30pc of our GDP, exports to the EU amount to about 15pc of GDP.

Yet this overwhelming bulk of the economy still has to comply with all EU regulations. Moreover, this non-EU proportion is rising all the time.
