My hon. Friend is exactly right. This is affecting businesses all over the country.
I want to make one final point. I have taken a lot of interventions because I know that many Members will not get the chance to speak later and they want to give their views. I am conscious, however, of the time. Time is running out in the negotiations and the clock is even sharper today.
The final reason given by those who object to a customs union is that it is a point of principle. They say that it is about our sovereignty and that that was at the heart of the Brexit vote. Even if it is bad for us, it is a point of principle that we should be able to set our own tariffs and sign our own trade deals, and that is somehow at the heart of the taking back control that Britain voted for.
I find that argument illogical as well as inaccurate because, as the right hon. and learned Member for Beaconsfield (Mr Grieve) said, any trade treaty involves signing away some sovereignty. Any kind of trade agreement involves legally binding conclusions and an independent dispute resolution procedure, and once the state has signed up to such an agreement, it might not be able to stop, for example, a US company taking contracts with the NHS or whatever we might have signed away as part of it.
Nobody wants to defend a principle of sovereignty whereby we never do any trade agreements with anybody or sign anything away. We should not do that because it would prevent us from getting a good deal with Europe that would help our manufacturing industry.
