HC Deb 13 November 1989 vol 160 c19W
Mr. Corbett

To ask the Secretary of State for the Home Department what powers prison governors have to forbid the loan of a postage stamp by one prisoner to another.

Mr. Mellor

[holding answer 10 November 1989]: Powers exist under Standing Order 4 and prison rule 47. One of their purposes is to prevent items, such as postage stamps, from being used as a form of currency within prisons.
