I wish to confirm that I did indeed say "May never". The noble Lord will remember as he was a member of the Government in 1986 who passed the first Act that introduced a similar clause to this. It has not been used very often since then. The Conservative Government had their own very good reasons for including this in the single European Act in the British national interest. It has not been used very often. We are in a different European Union with 27 members than we were then with 12, but it is unlikely to be used very often.
