Ms Suzanne Costello:

I will hand over to Dr. Kavanagh in a moment, but my observation in this arena is that there are excellent working relationships between colleagues North and South. As I mentioned, we are one of the maturer agencies. We know each other well. There is a lot of energy and impetus, but we lack the framework to deliver something meaningful. Everyone working in public health is very aware of the huge challenges that are coming down the line, particularly around the ageing population. We have a unit on ageing within our team. These challenges are immense. There is value, just as there is in business terms, in working in co-operation. There are the benefits of information sharing, but there are also cost savings in doing this together.
