Brave face, wishful thinking. Say what you like. We will still be buying stuff from the EU. Lots of it. There are not massive warehouses all over the world containing the same goods that the EU currently sells us, just waiting for 2019. We are not suddenly going to stop eating Camembert, driving VW Golfs, cooking with extra virgin olive oil, drinking Chianti and heating our houses with French electricity. It's facile to think that the world is replete with suitable alternatives for everything, all geared up to start supplying us (not tariff-free, lest we forget) in March 2019. We are highly dependent on doing business with the EU with our service sector and that will be severely hit by bureaucratic barriers that don't currently exist. Fears over brexit have hammered the pound, fired up inflation and stalled productivity and growth. It's anyone's guess how much worse it will look in 18 months' time. And WTO tariff rules are not a free-for-all, by the way.
