My Lords, I am grateful for the support of the noble Lords, Lord Purvis and Lord Callanan. I thank the noble Lord, Lord Purvis, in particular, for his ongoing—I will put it that way—interest in this issue. I very much welcome the comments of the noble Lord, Lord Callanan, on how vital it is that we keep our unity on these issues intact as we move forward. I am grateful and pleased that this is what we have seen today.
On the specific issue about the natural gas tankers, I am grateful to both noble Lords for their forbearance, as I do not have a full response on this today. The insurance is a complex issue. I will endeavour to get a fuller response by Friday. That is not a guarantee but, if I cannot get it by Friday, we will make sure that there is a response to the letter from Mr Duncan Smith.
I will do what I believe is called a pivot, to liquified natural gas more generally. I point out—because it is quite interesting and helpful, although it does not address the issue of insurance head-on—that Novatek, Russia’s largest producer of LNG, suspended production at its flagship Arctic project in April 2024 because of sanctions and a shortage of specialist tankers. This project is critical to Russia’s ambition to triple LNG production by the end of the decade, so we are taking measures that are having some effect on LNG. However, I will come back to noble Lords on the wider issue of insurance.
