I am going to press on, if the hon. Gentleman does not mind. I will take other interventions later.
I realise that all sorts of fanciful promises about new customs arrangements were made during the referendum and have been made since, but we have a duty to protect our economy, jobs and the manufacturing sector across the UK. That is at the heart of today’s debate. The only way to uphold that duty is to negotiate a customs union with the EU.
There is, of course, another important aspect. In December last year, our Government made a solemn promise in the phase 1 agreement: no hard border in Northern Ireland. And that was spelt out—no infrastructure, no checks and no controls. Now, in all the to-ing and fro-ing yesterday, what may have been
missed is that one amendment that went through, without any dissent from the Opposition, was a Government amendment to Lords amendment 25 for that obligation to be legally binding in UK law. That is a very significant amendment; after the political commitment in December to no hard border, no infrastructure, no checks and no controls, we now have a binding law to that effect. This goes to the issue of maximum facilitation, because if maximum facilitation does involve infrastructure, checks or controls, it would be unlawful under the provision passed yesterday. Therefore, it cannot happen.
