Order. I thank the Secretary of State for what she has said. Before I call the spokesman for the Scottish National party, I remind the House that in excess of 65 Members wish to speak in the debate, therefore there is a premium upon brevity, and the starting time limit for Back-Bench speeches will be five minutes each. I remind the House also that interventions should be brief. If Members want to know what the textbook is, they can consult the right hon. Members for New Forest West (Sir Desmond Swayne) and for Wokingham (John Redwood), to give but two examples, although the book may by now be out of print.
