I thank the hon. Gentleman for his intervention. As he will know, I have an interest in this area, and I wish to give assurances that this Government are taking alien species extremely seriously. We do not want invasive species coming into this country, and we will give assurances that we will have the highest level of protections and standards as we go forward, as this example today on plant biosecurity will demonstrate. This is a belt and braces step we are taking today.
