The son of a woman who was abused by a choirmaster as a teenager and took her own life said it is important to remember that counselling will "never be perfect".
Speaking about new proposals for a new code of practice for crime victims, Oliver Andrade said "trauma doesn't end at the end of a trial", he added, "it can be with people their whole life."
Oliver's mother Frances took her own life a week after giving evidence against choirmaster Michael Brewer.
