That is another thing I haven't got clear in my head - If companies currently use UK as a point of entry for import for distribution across EU27, will they want to incur two levels of tariffs in the future? How would this impact on ports. Would exporters want to do thorough the hassle of shipping to both UK and EU 27? As 88% of the market would be mainland Europe in the event of a drop in trade going through UK ports, where the money be found to maintain the employment levels of dock workers?
