The hon. Lady rightly raises the importance of the public health approach—having a legal requirement for all Government Departments and agencies to work together—but she is wrong to suggest that the only thing that has happened is the summit that the Prime Minister held. The hon. Lady will know that we have already published the consultation, which is ongoing. She will know that, to get good policy, it is right to hold a consultation. I hope that she will input into it and that, when it leads to legislation, we can have cross-party support.
