Two reports will be published on Wednesday into the death of Dundee toddler Brandon Muir.
The 23-month-old died at the hand of his mother's heroin addicted boyfriend, Robert Cunningham.
Earlier this year, the High Court in Glasgow heard that Brandon suffered a slow and painful death after suffering ruptures to his intestine in March last year at a house in the Douglas area of Dundee.
Evidence was also given that Brandon's mother, Heather Boyd, worked as a prostitute and smoked heroin on the night Brandon fell ill.
Ms Boyd was acquitted of the culpable homicide of her son by failing to get him medical treatment. Cunningham, meanwhile, was convicted of culpable homicide in March and sentenced to ten years in prison.
Following the case, child protection services in Dundee were condemned by Her Majesty's Inspectors in one of the most highly critical reports of its kind ever delivered in Scotland.
The government has since ordered "urgent improvements".
An independent report by former Fife chief constable Peter Wilson and a statutory one by James Hawthorn, an independent social work consultant, will be released in Dundee on Wednesday.
The report by Mr Wilson was commissioned by the chief officers of the Dundee Children and Young Persons Protection Committee - which include Dundee City Council, Tayside Police and NHS Tayside - following Brandon's death.
Mr Hawthorn's report, a Significant Case Review, is a statutory requirement in such circumstances.
