The father of murdered child James Bulger has questioned why one of his killers Jon Venables continues to be granted lifelong anonymity after caught with indecent images of children.
A parole report found Venables, now living under a different identity, used sex and pornography to cope with a "lack of fulfilment in life".
Despite being denied parole in 2020, Venables is now hoping to be granted freedom in a matter of weeks.
James' dad Ralph has questioned why Venables continues to be granted anonymity, with a debate due to take place in Parliament.

He said: “I said from day one that the attack on James was sexual but because the killers were just ten, no-one could get their head around it.
"The evidence was there, but it was swept under the carpet.
“The public deserves to know everything about this case including why those in authority believed they had been rehabilitated."
James Bulger was tortured and killed by the men formerly known as Venables and Robert Thompson – who were both aged 10 – after they snatched him from a shopping centre in Bootle, Merseyside, in February 1993.
Thompson and Venables were jailed for life but released on licence with new identities in 2001.
Venables, 36, was sent back to prison in 2010 and 2017 for possessing indecent images of children.
He has been serving a 40-month sentence which passed the halfway mark last October.
Mr Bulger has now called for a public inquiry into Venable's lifelong anonymity.
He also told the Mirror: "A public inquiry is long overdue so we can flush out the truth about so many issues.
“But top of my list must be why Venables is still one of the very few people in this country who still has lifelong anonymity despite his repeated offending against children.
“I don’t buy the argument that his life would be in danger. If that was the case, they would have to give secret identities to every child abuser and killer in the UK.”
