His bright idea was to use some of the same counterfactual economic models that appear to show Brexit has done huge damage to Britain. But he, rather naughtily, applied one of those models – that Remainers love to cite – to data for France, Germany and Italy. What he found was rather comical. That our EU neighbours by this scenario come out worse than Britain does: France “loses” 7 per cent of GDP and Germany “loses” 12 per cent – far more than the 4 per cent “loss” the model shows Brexit is supposed to cause Britain.
