My hon. Friend is absolutely right on mental health and where a patient is violent, as I saw for myself on my visit to Bedford, for example, that can be unsettling for A&E. I am happy to have further conversations with him on what measures can be taken. The fact is there is no single intervention in this space; it is a question of looking at the integrated approach. That is what the call for evidence is about. Also key is understanding the data and seeing where it can better target action on areas such as mental health that can have a disproportionate impact.
