I entirely agree with the last point that the leader of Plaid Cymru has made, Llywydd. The UK Government has moved to prevent access to UK ports by vessels using the Russian flag, and it did so because there was a vessel about to embark in Scotland under those circumstances. I think it is inevitable, Llywydd, that in such a very fast-moving picture, when Governments take one action, attempts will be made to try to subvert it and get around it. When those loopholes are identified, the UK Government will need to act again to make sure that the intent of their policy, which clearly is to prevent Russian oil being disembarked at UK ports, is effective, and when there are loopholes or ways around the rules that are found—and it is inevitable that others will seek that—that the UK Government gets that information as fast as possible and is then able to act on it equally quickly.
