To ask the Secretary of State for Justice what assessment he has made of the pilot study of drug-free prison wings; and when he intends to publish the outcome of that project.

The Government is committed to increasing the number of drug free wings in prisons, where increased security measures prevent access to drugs.

Evaluation of the pilot of these wings will begin once the pilot concludes at the end of September. I expect the evaluation to be completed by the end of March 2014.

I will consider whether and how to publish the evaluation carefully. It may be that publication of the evaluation, containing details of measures that are effective in reducing drug availability in prisons, could compromise the effectiveness of those measures if they are placed into the public domain.
