HC Deb 30 March 1960 vol 620 c128W
Mrs. Castle

asked the Minister of Defence to what extent the techniques of brain-washing, described by Professor Kennedy in his lecture to the Royal Institution, have been used by Her Majesty's Government in any of the theatres of operation of Her Majesty's forces, either during or since the last war.

Mr. Watkinson

I know of no case where any of the Services has used the techniques described by Professor Kennedy.
