Exactly. Presumably the Government think they can negotiate on that between the UK and the EU bilaterally, but actually that is not the way that this works. Under the WTO arrangements, we have to make sure we have the same application of rules as we would in other arrangements around the world.
A customs union is not just preferable; it is the only realistic option. The idea that the European Union is going to say, “Fine, we’re happy with you splitting the four freedoms” is for the birds. That is not going to happen, especially as populism is running riot worldwide. The EU feels very firmly that it wants to defend the international rules-based system. It feels very firmly that the four freedoms of the single market and the customs union are integral to it. The idea that Switzerland provides an example, when it has endured decades of constant treaty negotiations year after year after year—that is not a model Britain should seek to parallel.
The idea that we should simply hope that by focusing on the withdrawal agreement we can secure our future is also a fallacy. The notion that we will be able just to staple on to the back of this arrangement, on a few sides of A4, political statements on our future relationship
with the EU is deeply dangerous. We have to make sure that we settle these issues—I know the former Brexit Secretary agrees on this particular point. The idea that what is said on one side of exit day will necessarily be enforced on the other side of exit day is just not true. There is no legal enforceability to any warm words about our future relationship. These issues have to be set out at this particular stage.
