I am glad to be able to speak in this debate, which was secured by my right hon. Friend the Member for Normanton, Pontefract and Castleford (Yvette Cooper), the right hon. Member for Loughborough (Nicky Morgan) and other Chairs of Select Committees.
A number of issues have been raised. In the interests of time, I do not propose to go over them, but they include the issue of no new barriers, the wider issues of regulatory convergence, the need to continue the ease of our trade and the dream of independent free trade agreements closing the gap created by what we will lose as a result of leaving the European Union, the single market and the customs union.
I want to raise a few of the wider economic issues that have not so far been addressed in this debate. The predecessor to the EU customs union first came into being about 65 years ago with a treaty establishing the European Steel and Coal Community. Some people seem to think that that makes it an anachronism. There is also an argument that the UK is now mainly a services economy, so an agreement that eases trade in goods is no longer as relevant as one that eases trade in services.
Putting aside the fact that goods remain around half of UK exports and so are still important and essential in their own right, the argument fails to grapple with the complexity of the modern economy that any stark dividing line between goods and services is false. Being in the customs union has relevance for services as well as for goods.
The UK economy is bound up in a complex network of EU supply chains for producing intricate products such as cars and pharmaceuticals. A substantial share of the value of these goods, ranging from 20% to 40% across most regions, according to estimates from the UK Trade Policy Observatory, is the services that go into them. Therefore, when a car rolls off the production line in Sunderland, Ellesmere Port or Luton, the value of that car includes the cost of accountants, administrators and auditors who the car company employs in making it. These services are then exported indirectly when we sell these cars abroad. Therefore, it is not only the goods but indirect services exports that rely on a near seamless passage that the customs union provides.
