Samuel Lowe at the Centre for European Reform makes the case for the UK to stay in a customs union with the EU after Brexit. It'll be much better than Turkey's current customs deal, he writes: "Being a in a customs union, and in particular one with the EU, would constrain the UK’s ability to sign new trade agreements. From a macroeconomic perspective, this is of little relevance: even the government’s own analysis find new FTAs will be of small benefit to the UK’s economy, compared to the cost of Brexit."
