It is always a pleasure to be patronised by the noble Lord, Lord Davies. As someone who passed only parts 1, 2 and 3 of the Institute of Statisticians exams, I suppose that I must give way to him if he passed part 4. I fully know the difference. If he looks, for example, at a group of countries which are at a similar level of development to ours and which trade with the EU single market, he will see that their exports rose significantly more than ours did over that 25-year period. I do not know quite why that is but it is clear that trading within the single market has not had such a big impact on our exports to the rest of the EU as I certainly expected it to have at the time and as he believes in retrospect it has had.
