Well, Llywydd, I learnt of this data breach yesterday, and I learnt of it as a result of Public Health Wales's statement, which, as Paul Davies has said, drew attention to the data breach. It is a serious matter when data regulations are not properly observed, and I think Public Health Wales was right to apologise to those people whose data was inadvertently put into the public domain in this way. Thankfully, as Paul Davies said, the breach lasted for less than a day and the initial inquiries suggest that no harm has been done as a result. But that is a matter of luck rather than anything else.

It's right, therefore, that Public Health Wales has instituted an inquiry into what went wrong, has informed the Information Commissioner, and we will look to both of those offices to make sure that the reasons that lie behind the data breach can be identified, and if there are any systems that need to be put right, that those steps are taken rapidly.
