I think that the concept of something that is seriously prejudicial to the interests of Her Britannic Majesty—to the interests of the United Kingdom—will be understood. There will of course be an opportunity for a review of that through a court process—a judicial review—so the definition would be tested. My hon. Friend might not choose to rely on the abilities or understanding of future Home Secretaries, but I hope that he will see that there is a further safeguard.
I wish to reiterate—this is an important point—that that is the position the United Kingdom had prior to 2003, when the law was changed. It is the position that we are required to have under the United Nations convention. All that we are doing is returning our position to the scope of our declaration under that convention. It goes no further.
