The hon. Lady is absolutely right. Health in all policies means using every opportunity to maximise public health. When Departments work together, such as on the childhood obesity strategy, we need maximum engagement across the whole of Government to make that effective. The way it was put to us when the Committee visited Amsterdam was that it should be viewed as a sandbag wall, and if any part of it is missing, we are not going to achieve what we want. That applies to all of public health.
