Again, I am going to have to stray into areas for which I do not necessarily have the detail, because the clinical operation of clinics is obviously a matter for the NHS. My understanding is that under-18s cannot make those kinds of decisions, but I am looking for guidance from officials in case I get this wrong. It is probably safest for my hon. Friend to let me write to him with specific details of the clinical guidance on how under-18s are supported, but my understanding is that under-18s are not permitted to make irreversible decisions. Let me write to him regarding the exact line for decision-making capacity with parental involvement, so that I can get it absolutely right for him.
