My right hon. Friend is right that SMEs, particularly in the component supply chain, are the most vulnerable to these sorts of changes. They are the most likely either to lose business elsewhere or to have to move abroad. I can give concrete examples where that has already taken place.
The right hon. and learned Member for Rushcliffe described the apparent view that the customs union is some sort of problem holding us back. He is right that it has not held us back. The likes of Germany, which exports 10 times more to China than we do, are in the customs union, which has not been to their disadvantage. As he said, we have witnessed the most phenomenal explosion in the success of the automotive industry in this country over the past 10 years—after 20 years of relative stagnation, it grew by more than 50% in that period.
In summary, where it is rare for businesses to speak out, we should listen. They do not intervene lightly in politics, in this country or elsewhere. The preservation of a true customs union is critical to safeguarding business and investment in this country, and that is why I support new clauses 1, 11 and 12.
