Finance (No. 2) Bill

I wonder if my right hon. Friend would like to say a word about the extent of research the Treasury already undertakes and publishes. It is my understanding that more than 2,500 Treasury papers have been published, so it is really a question, is it not, of where we draw the line? If a piece of research is proving very difficult, and would be very resource-intensive and so on, that will obviously make it less likely to be done than if it is a more straightforward piece.
