My Lords, I thank the Foreign Secretary for his Answer. There is no doubt that sanctions are having an impact. Indeed, you only need to look at the Russian-flagged tankers languishing in harbour; that is why Russia has to have this shadow fleet. My question relates directly to the shadow fleet. Thousands of these ships are being operated, many of them under flags of convenience. They are not properly insured or maintained, and they are at the bottom end of the spectrum. Many of them are going through the Great Belt without pilots, coming down the North Sea and through the channel and doing transfers in the Atlantic. It is a recipe for a disaster which will not be properly covered. We have huge clout in this country because we run merchant shipping, really: we have the insurance, all of the lawyers who work in this area and the IMO. Is there more that we can do to screw this down to put even more pressure on Russia? The Chinese are careful because of secondary sanctions. Could we do more to try to stop this?
