HC Deb 31 March 1930 vol 237 c898
69. Mr. CECIL WILSON

asked the Home Secretary how many of the persons sentenced to death in England and Wales during the 10 years prior to 1929 had their sentences of death commuted on the ground that they were certifiable as mental defectives under the Mental Deficiency Acts?

Mr. CLYNES

No case can be traced in which that was the sole ground, but in various cases a degree of mental deficiency was considered, with other grounds, in advising commutation.
