Where has the change occurred in the journal being identified as being of no evidential value in the investigation? I am trying to recall on the hoof, but in engaging with the family and their solicitor I understand they have been informed the journal is of no evidential value. Why can the solicitor and the family not be furnished with the journal in a redacted form, or confidentially, in the understanding it would not be released publicly?
