My Lords, is the Minister concerned about the erosion of nuclear arms control, as evidenced by this statement of intent by President Trump following his determination to resile from the nuclear arms deal? Added to that is the uncertainty about the renewal of the Strategic Arms Reduction Treaty. In all those circumstances, what prospects does this demonstrate to us for the review conference in 2020 of the nuclear non-proliferation treaty? What work are the Government already embarking on in relation to that review?

My Lords, it is difficult to think of a more difficult foreign policy issue that the Government must now face. I cannot think of anything as serious from all my time as either a Member of Parliament or a Member of your Lordships’ House. Difficult circumstances and challenges often give rise to opportunities, however. The noble Lord, Lord Hain, put his finger on it when he said that this is an opportunity to reset our relationship, not just with Saudi Arabia but with other countries in the Middle East to which we have for many years adopted approximately the same attitudes and positions.

I shall make two other, perhaps unrelated, points. What could be more sinister than the fact that among the 15 who came to the consulate was a forensic pathologist? What possible purpose was he meant to serve by being part of the 15? I think we could all make a pretty good guess.

On the other hand, the Minister rightly referred to the intelligence relationship. When he was Prime Minister, David Cameron publicly—surprisingly but, in the circumstances, he thought necessarily—acknowledged that information provided by the Saudi Arabian Government directly prevented an enormously difficult and potentially very damaging terrorist outrage in this country. It is the balancing of these two issues that gives rise to the Government’s difficulty. However, I take the view that as soon as all the necessary information is available a judgment must be made—but I would in no way support the notion that we should conduct a running commentary or offer a step-by-step approach. We need to deal with this matter as a whole, once a proper judgment has been reached.

My Lords, no doubt inadvertently, the Leader did not respond to the final point made by the noble Lord, Lord Hannay. Do the Government accept that during the period of implementation or transition—call it what you will—the United Kingdom will be subject to the jurisdiction of the ECJ and that that jurisdiction will also last for as long as any extension to that period of transition?

Is this issue part of the defence modernisation programme, which is of course a defence review by another name? The results of that review were promised in June this year. So far, no results have been published. What is the reason for the delay, and when will the results be announced?

To ask Her Majesty's Government what steps they are taking together with other members of the European Union to mitigate the effects of the imposition of sanctions on UK companies doing business in Iran.
