Prisons: Drugs Philip Davies To ask the Secretary of State for Justice if he will publish the updated Supply Reduction: Good Practice Guide issued to prisons in England and Wales. Maria Eagle The “Prison Drugs Supply Reduction—A Good Practice Guide” contains detailed information about the methods and tactics employed for disrupting the supply of drugs in prisons. As such, in its entirety it is a considerable asset to those wishing to smuggle drugs into prisons. Publication would, or would be likely to, prejudice the maintenance of security and good order in prisons. We therefore have no plans to publish the guide.
