Two years after Baby Peter died in a blood-spattered cot, campaigners are still seeking assurances that another child will not "slip through the cracks".
The little boy's death at the hands of his mother and "stepfather" in Haringey, north London, on August 3 2007 is continuing to send shockwaves through child protection agencies across the country.
Local Lib-Dem MP Lynne Featherstone said there were still many unanswered questions two years on.
"This is a sad time when we remember a tragedy that should never have happened," she said. "Those people involved in the evil cruelty that led to Baby Peter's death have been punished, but I am still deeply concerned about Haringey's children's services that failed to protect him."
Peter was just 17 months old when he died, having suffered 50 injuries despite receiving 60 visits from social workers, doctors and police over the final eight months of his life.
There was widespread outrage when the full facts of the case emerged in November last year, at the end of the trial of those responsible for his death. Review after review identified missed opportunities when child protection staff could have saved the little boy's life if they had acted properly on the warning signs in front of them.
His mother, 27, who cannot be named for legal reasons, was given an indefinite sentence with a minimum term of five years at the Old Bailey in May after pleading guilty to causing or allowing her son's death. Judge Stephen Kramer described her as "manipulative" and "calculating" while rejecting her claim that she was too naive to realise what was going on in her house.
Her boyfriend, 32, was jailed for life with a minimum of 10 years for raping a two-year-old girl and also given a 12-year term to run concurrently for his "major role" in Peter's death. The couple's lodger, Jason Owen, 37, of Bromley, south-east London, received an indefinite sentence with a minimum term of three years for failing to take steps to save the little boy.
Public anger and official censure initially focused on social workers at Haringey Council - the same local authority that was severely criticised for failing to prevent the murder of eight-year-old Victoria Climbie in 2000. Haringey's child protection services were condemned as "inadequate" in a damning report commissioned by the Government after the Baby Peter tragedy. In response the council's leader and cabinet member for children and young people resigned, and its children's services director, Sharon Shoesmith, was sacked.
Inspectors went back into Haringey to check whether things had improved, but they warned last month that the council was still not protecting all vulnerable children from abuse.
