I could bore for Britain on supply chains. It was one of the academic subjects that I looked at, globally. As we become more economically efficient and supply chains become more efficient, they become more brittle. We saw how the shops were affected by lockdown and by China, and much of the manufacturing, as part of that supply chain, started in China. Companies across the world have looked at different options. Some have looked at sourcing elsewhere; some have looked at stockpiling; some have looked at reshoring; but all those options add considerable costs to the supply chain. Some have even looked at intermediary solutions, including warehousing in cheaper countries and then bringing the goods in closer. I am very happy to go on at length to the noble Lord at any time, but not now.
