My Lords, I would like clarification from those who tabled this amendment: they refer to “a” customs union but other speakers have used the expression “the” customs union, as the noble Baroness, Lady Altmann, has. For the purposes of what I am going to say. I will assume that they mean remaining in the EU’s customs union and common commercial policy.
If that is the case, I understand the motivation for seeking a halfway house between leaving and remaining, which is what this implies. However, being in a customs union and being entirely subject to the EU’s common commercial policy, which is the overarching umbrella under which the customs union sits, is the worst of all options. That is why Switzerland and Norway—two countries with different arrangements in the EU—have chosen not to be part of the customs union. So while the idea may be attractive to protect trade in goods—and I admit that is important—given that we have an economy where trade in goods is a relatively small part of our exports, the sting of the common commercial policy, although it is encroaching into services, is primarily about trade in goods, not trade in services.
Being under the umbrella of the CCP without membership of the EU will mean that we will not be present in the European Council, which has the ultimate say over trade deals; we will not be present in the
European Parliament or in regional parliaments. Noble Lords may remember the Canada-CETA story and the Parliament of Wallonia. We would not even have the status of the Parliament of Wallonia in future trade deals were we stay in the customs union. We would be a rule taker without a seat at any table. It would also render the previous amendment, which the House overwhelmingly passed, entirely redundant.
Turkey feels so disadvantaged by its current arrangement in the customs union—which, incidentally, was only agreed as a stepping stone towards full membership—that it is seeking to change those terms. However, I suspect that by now it is not seeking to change the terms because it accepts that it is not going into membership of the European Union.
The CCP is designed to serve the interests of member states—and so it should—but it is not designed to serve the interests of the fifth biggest economy in the world. Even those who feel that the United Kingdom will be much diminished if it leaves the EU must surely recognise that we are a more significant economic power than Turkey. So when the EU rightly seeks to advance its own interests, who will speak for UK interests? When the EU moves to use trade remedy laws—we have had a great deal of discussion during the passage of this Bill about trade remedies—to protect its own industries, and when that does not cohere with the United Kingdom’s interests, while we remain a member we can say something about it; we can indicate our preferences. If we are out of the EU but within the customs union, we would have no say over our interests being disadvantaged in the interests of any of the 27 member states which would be at the table.
