That is a contingency which we have to face all the time. It is hardly feasible that the whole of a filling factory could be blitzed, because in some cases there are over 1,000 separate shops, so designed that a hit on one would not affect the others. While it is only prudent to consider the possibility of a factory being blitzed, I submit that one can be too cautious in making provision for that contingency. My right hon. Friend then dealt with the recommendations regarding redundant labour. In my judgment, and this is purely my own personal opinion, I should think that some 20,000 to 30,000 unwanted persons in Royal Ordnance factories could be transferred.
