Mr. Derek Tierney:

If we go back to the start of my conversation, thinking about the current landscape, we have data on Deputy Cullinane, depending on what care he has been given in different parts of the system. It is not joined up. In parts of the system, what is thought about is what care is being given to Deputy Cullinane in that locality. He could be accessing care at the other end of the country and there may be a number of different identifiers associated with him. What the PPSN is try to do is bring it all together to say-----
