Health and Social Care Bill

My Lords, I have a question for the noble Earl on this amendment. What will be the relationship of Public Health England, the national body that will take over the functions of the Health Protection Agency and other areas, to the national Commissioning Board? I wonder whether the noble Earl can guide me to the statutory framework for Public Health England, as it does not seem to be in this long Bill, although it is possible that I am just incompetent and have not spotted it. It seems to me that the chief officer—I hope that he will be a highly qualified public health specialist—who is the senior officer in Public Health England, should have a seat on the national Commissioning Board. That should perhaps not necessarily be permanent, but he should be consulted frequently by the Commissioning Board.
