One of the schoolboy killers of toddler James Bulger is today meeting a parole board panel which could order his release from custody.
Jon Venables could be freed within days if the panel decides he is no longer a risk to the public.
Robert Thompson, Venables' partner in the February 1993 murder, will attend a separate hearing on Wednesday.
Lord Chief Justice Lord Woolf effectively ended the boys' tariff - the minimum period they must spend in custody - last October.
He ruled that it would not be beneficial for the boys to spend time in the "corrosive atmosphere" of an adult prison.
The teenagers were also granted an open-ended High Court injunction protecting their anonymity when they are freed from detention with new identities.
Ms Dee Warner, of pressure group Mothers Against Murder and Aggression, says protesters will hold a demonstration outside the Parole Board's London headquarters.
The families of murder victims will be among the crowd, but James's parents, Mr Ralph Bulger and Ms Denise Fergus, are not expected to attend.
Ms Warner said: "Is there an expert panel that is going to give us a 100 per cent guarantee that they will never commit another offence like that?
"Is anyone going to be held accountable if they do commit a new offence?"
