Maria Davies' partner Martyn Rogers was one of eight patients whose deaths were 'avoidable' at Cardiff hospital. She has told ITV News about the loss on what would have been his birthday.
Maria said she blames Professor David Berry for Martyn's death: "He didn't just take Martyn's life, he took mine as well. I'm nothing without him now. I just want the answers, I just want to know why they took him."
