Corporate Manslaughter and Corporate Homicide Bill

My hon. Friend the Minister is right to describe what has been happening in the Prison Service. It is equivalent to what has happened in the NHS in an attempt to reduce deaths from clinical error. However, the Bill means that if a hospital fails to supervise its doctors effectively, it can be convicted of corporate manslaughter. What is the difference between that institution and a prison, another public institution that needs to be competently run according to the test laid down in this legislation?
