I thank the shadow Minister, the hon. Member for Kingston upon Hull North (Diana Johnson), for her welcoming me to the Front Bench on this matter, and I agree that the key issue is that the EU basis, suggesting there is an impediment to legitimate trade, is completely wrong. That is why the EU proposals are unacceptable.
The early-warning system does work. In fact, I referred AMT to it only a week or so ago, when my hon. Friend the Member for Winchester (Steve Brine) prompted me to do so. The early-warning system is also activated in terms of Exodus Damnation, so that we can see what can be done about that. What we have done successfully in this country is ban families of substances, and even substances that do not exist, in anticipation of what might come next.
