Comparable figures for the various years are not available because the basis of accounting and methods of provision have changed. Such figures for earlier years as are available have been published in the annual reports of the Commissioners of Prisons. I will, with permission, circulate figures for 1963 in the OFFICIAL REPORT, together with an explanation of the basis on which they have been calculated. As I have said on many occasions, I am extremely anxious that prisoners should be employed more productively, but the level of expenditure on prison services does not depend on this.
