Mental Health Units (Use of Force) Bill

I am grateful to my hon. Friend for bringing forward this very important Bill. Many families in my constituency have contacted me, including some affected by autism, and they are very concerned about the kind of face-down restraint that he has described so movingly in talking about this case. Does he agree that it is very important to have boundaries on the use of this restraint, and that families have some certainty about what can and cannot happen in such facilities?
