It was a week when reality bit, and bit very hard. Brexiteer illusions about a world of easy free trade deals beyond EU membership took a heavy hit when the US slapped a 219% tariff on Bombardier, the Canadian plane maker, over alleged illegal state aid, putting 4,000 jobs in Northern Ireland at risk.
Then, on Friday, the economics editor of SKY TV reported that close on 10% of UK exports was made up of gold which was simply recycled through London. As most of this went to non-EU countries, such as Switzerland, India and China, it had the effect of understating the value of UK manufacturing exports to the EU. The figure is closer to 50%, rather than the 44% quoted by the Brexiteers. The UK does not export as much to the rest of the world as it thinks it does.
