I am grateful for the hon. Member's explanation. I feel that if he is curious on this matter I should procure for him from His Majesty's Stationery Office a copy of the illustrated book which deals with some of the matters to which he has referred. My intervention in this discussion is not with a view to enlarging on the faults, if any, or virtues, if any, of the National Coal Board. The hon. Member for Sutton Coldfield has raised the question of whether we are getting sufficient information from the former Minister of details of management and other business of the National Coal Board. He has raised a powerful and impressive argument that satisfies me that we are not getting that information. I am not so sure that the House, when it reflects on this matter, will want the information for which my hon. Friend makes such an eager claim. When the nationalisation of the coal mines came before this House and became the law of the country, I was among those who demurred at the policy. The policy of nationalisation of the mines seemed to me then; as it does now, to be unwise, a foolish one and probably an ill-starred one, and what I have heard this afternoon shows that these doubts and anxieties are not held only by me in this House.
