A Customs Union isn’t the way out of the Brexit mess

For some of those desperate for Britain to stay put in the EU, the Customs Union option functions as a handy obsession. Ministers, too, appear to be rallying behind this as a solution to the Brexit crisis, amid reports that dozens of senior Tories could vote for the UK to stay in a customs union in tonight’s vote. They are making a big mistake.

There is no substantive case for irrevocably and permanently subjecting Britain to the European Union’s Customs Union. Rather than attempt to demonstrate how being tied to the Customs Union furthers the national interest, the best its proponents can do is pitch it as a tactical compromise. Being part of the Customs Union would mean effectively ceding the right to a foreign power to determine Britain’s trade and commercial policy in perpetuity. In setting tariffs on British imports, it would subject Brits to taxation without representation, the issue that sparked American independence.
