Domestic Ivory Market

First, I thank the right hon. Gentleman for actually producing some evidence with that £500 figure. He will not be surprised to hear me say this, but it looks like having a certification system at £500 a pop for pre-1947 ivory is the way forward to balance things. He has spoken passionately, and I hope he gets on to this matter. I asked the hon. Member for East Kilbride, Strathaven and Lesmahagow (Dr Cameron) for some evidence that a total ban on the domestic ivory market, which is what the debate is about, will stop or lessen considerably—hopefully to zero—the poaching of elephants. I am not getting a causal connection there, because I am not hearing the evidence.
