Answering a question on why Ian Brady should not be detained in hospital, Dr Adrian Grounds said: "There's a high degree of tolerance of some unpleasant parts of his behaviour in hospital.
"There might be less tolerance in prison."
Dr Grounds added: "If one thinks he has capacity for autonomy it would be wrong to stand in his way".
He added: "But it would be difficult to recommend something that you think would have consequences for him. So I would not recommend one or the other. I would not actively oppose him going back to prison.
"In Mr Brady's case, this is primarily a wish to have control".
