I know that the hon. Gentleman takes a close interest in drug treatment in his Constituency, where he has an excellent record on the subject. Responsibility for such treatment in prisons has been transferred to the NHS. I agree with his proposition that clinical judgments must lie at the heart of any drug treatment programme, but it is necessary for Departments to collaborate. My right hon. Friend the Secretary of State for Health and I hope to produce a combined framework on treatment in prison and treatment for convicted drug users in alternative residential accommodation. That might include the transfer of prisoners in suitable cases to community-based mental health care. All those things must be tried, because the current situation is quite appalling. However, in the end, treatment of an individual must be a clinical decision. It is certainly not a decision for politicians.
