The tariff barriers between us are now low – down to 3 per cent. But it is the non-tariff barriers that need to be blown away, the fiddly stipulations that are furtively used to keep out foreign competition. If we can get the EU-US free trade pact done in the next 12 months, we will boost the British economy by about £10 billion per year, and boost the whole of the EU by £100 billion. That is not to be sneezed at – not when the eurozone is once again dangling over the lip of a downturn.
