I thank my hon. Friend for his decades of service to this House and the country. The work that his Committee has done in particular is considerable. I served on it briefly, for about three years, and in our first sitting I needed a trolley to get the papers for the meeting to the relevant Committee Room. It is a huge amount of work, and we have been enormously helped by his attention to detail and huge expertise in this area. On many highly technical issues, he often turns out to be right. I am aware of the issue that he raises, and have expressed my interest in it to the relevant Departments. He leaves a great legacy in this place, and whatever the future holds, I am assured that the issues that he cares deeply about—of course, in large part due to his efforts, we now have opportunities and freedoms to exploit, and can enjoy and protect the interests of this country—will be in good hands, and that is largely down to him.
