First Minister, obviously any test and trace system requires confidence in the sharing of information. You've been asked twice this afternoon about the data breach that occurred in Public Health Wales—a substantial data breach. On the one question that was put to you, you were asked, 'When did the Government get alerted to the fact that this data had gone in to the public domain?' You failed to answer that question, so could you respond to my question, please, by providing an answer: when was the Welsh Government—not yourself, the Welsh Government—informed of this data breach and who in the Welsh Government was the first point of contact in the ministerial ranks to be alerted to the fact that 18,000 names had been put in the public domain?
