I will press on, make my case and take some further interventions later on.
I was saying that the proposal in Lords amendments 1 and 2 that the Government should seek to negotiate a customs union with the EU as part of the future arrangements is a sensible one for many reasons. The first is the economy. Over a number of decades, our manufacturing model has adapted to the arrangements that we currently have with the EU, including the customs union. Thus, typically, we see, across the UK, thousands of manufacturing businesses that operate on the basis of a vital supply chain in goods and parts from across the EU. The car industry is an obvious example, but not the only one.
Such businesses operate on the basis of a just-in-time approach. Whereas years ago there were stockpiles of parts and so on, these days there is a just-in-time approach. Parts come in and are assembled, and the finished product then goes quickly and seamlessly across the UK and/or out to the EU. That is the manufacturing model that this country has operated for many years, and MPs across the House know that that is what goes on in their constituencies.
