I'm grateful to the Minister for his answer. The Minister will be aware that the management of Betsi Cadwaladr university health board has recently acknowledged to the families at Tawel Fan that the unit was, in fact, a dementia assessment unit, and, therefore, nobody should have been living there long term, though some patients were there for more than six months. Can the Minister explain: do we have an understanding as to why this was allowed to happen? And is he confident that no other patients in Betsi Cadwaladr in any other settings are being accommodated long term in units designed for short-term assessment stays?
