My Lords, the noble Lord, Lord West of Spithead, said that this is a timely debate. In some ways it is very timely, and in other ways it feels somewhat out of date.
We have just finished a debate on a report about treating students fairly from the Economic Affairs Committee of your Lordships’ House. It was also published in the summer of 2018, and has aged quite well in the last six months—very little has changed. In terms of the report from your Lordships’ European Union Committee on the proposed UK-EU security treaty, everything and nothing has changed. The noble Lord, Lord Jay, said when he opened this debate that in many ways he was not going to look at the report precisely because so much has changed.
When that report was written, it was very clear that security co-operation was essential, as we have heard from across the Chamber this evening. But it was also clear that security co-operation was not guaranteed. The idea that it is not a zero-sum game is important, but it is also important to understand that the law of unintended consequences—as the noble Lord, Lord Kirkhope, suggested—is a real risk. In July last year when the report was written, the Government and the committee were working on the assumption that there would be a withdrawal agreement and a transitional arrangement which would take us to the end of 2020. The report, and the Government’s response, were written in that vein.
What we have seen in the last two weeks in the other place suggests that neither of those things may happen; we may not have a withdrawal agreement, and if we do not then we will not have a transitional arrangement. If security needs to be continuous, if there should not be a single minute between the arrangements that we have now and where we are when we leave the European Union, what is the Government’s plan if, on the

Even if a withdrawal agreement of some sort can be salvaged between now and March, what confidence can the Government give us that there will then be a security treaty in place leaving the United Kingdom and EU 27 as safe then as we are today?
Finally, can the Minister begin to tell us how we would get to that situation, given that some of the key aspects, as the noble Lord, Lord Jay, has made absolutely clear would be essential, include the jurisdiction of the Court of Justice of the European Union? That was one of the key reasons the deal was voted down in the other place; it was not just about the Northern Ireland backstop. That is going to be an issue for a security treaty as much as the withdrawal agreement. Can the Government give us any assurance at all that we will be secure?
