The mother of Baby Peter has been jailed indefinitely for causing or allowing the toddler's death.
Her 32-year-old boyfriend was jailed for 12 years for causing the toddler's death and for life for raping a two-year-old girl. He must serve at least 10 years.
Many different people in authority gave their reaction after the sentencing.
ED BALLS, CHILDREN'S SECRETARY
"What I can't do is make a commitment that I can stop adults harming children, because I don't have that power.
"But where it comes to the attention of the social worker, the police officer, the GP, the paediatrician, they should act to put the child first and not be deceived by parents covering things up when there's actual harm there right in front of you, staring you in the face as happened with Baby Peter."
LYNNE FEATHERSTONE, HARINGEY MP
"The guilty have at last been punished, but we still cannot rest until we fully understand how this poor little boy suffered so terribly, and for so long, under the noses of Haringey's children's services.
"The first serious case review either showed clear incompetence or was a cover-up.
"This one could not be more different from the first. It says exactly what we should have learnt at the start of this awful tragedy - Haringey Council, health professionals and the police all failed to protect Baby Peter from three individuals who set out to harm him.
"Seven months after light was shed on these failures, the focus on children's safety must never drift again."
CLAIRE KOBER, HARINGEY COUNCIL LEADER
"We failed these children and I apologise unreservedly for the shortcomings and mistakes in our child protection service in 2007 when these crimes were committed.
"We are making urgent and substantial improvements to the service and we will act on recommendations set out in the two serious case reviews into both of these cases."
MARGARET EATON. LOCAL GOVERNMENT ASSOCIATION CHAIRMAN
"The appalling story of what happened to this little boy has shocked and saddened people all over the country, in every walk of life.
"The individuals responsible for this child's death are now being punished for what they did.
"Protecting vulnerable children is one of the most important jobs local councils do and they are committed to doing it as well as they possibly can."
ANDREW FLANAGAN, NSPCC CHIEF EXECUTIVE
"We are disappointed that the minimum tariff was so low. It raises the question of how bad the abuse has to be before offenders get a longer minimum time in prison.
"Baby Peter suffered sustained abuse leaving him with horrendous injuries. Two of his abusers could walk free at a time when Peter should be a schoolboy with a new world in front of him. Despicable cruelty has denied him that opportunity.
"These three caused or allowed the torture and death of a defenceless baby."
