Thank you, Minister, for that answer. You'll be aware of the case of my constituent, Barry Topping-Morris. He was caught up in events surrounding the release of a patient from the Caswell clinic in Bridgend who went on to commit homicide. Mr Topping-Morris has long raised concerns about the investigation of these events and the impact they had on his own subsequent career. What assurances can you give him that lessons have been learnt from previous events and that an investigation of any similar event today would be conducted to contemporary standards? And would you be prepared, Minister, to offer an apology to Mr Topping-Morris and his family for the distress that they've been through over the last many years since this complaint was first lodged?
