This deeply saddening case reveals a host of issues that go far wider than just the mother of Hamzah Khan. More than anything this case highlights how small but timely interventions at crucial points from professionals, but from the public too, could have prevented this tragedy.
It is utterly depressing that the first time all the information about the risks in Hamzah’s life were pulled together is a report which has only been written because he is dead. No one professional held all the information whilst he was alive to pull together the fuller picture that might have saved him.
Professor Nick Frost, chair of the Bradford Safeguarding Children Board, who led the serious case review into Hamzah Khan's death has said it is is his responsibility to "ensure lessons are learnt".
"Very sadly, I cannot give assurances that a tragedy like this will never happen again in our country - as we can't control or predict the behaviour of all parents, the vast majority of whom are doing their very best to care for their children.
"However, I can assure you that at this stage I am satisfied each agency is responding adequately but this is an ongoing process which requires constant monitoring.
"No child should go through what Hamzah experienced. I am satisfied that systems are in place today that minimise the chance of a situation such as this ever being repeated in Bradford."
Following the publication of a serious care review in the death of four-year-old Hamzah Khan, the children's minister Edward Timpson has written to Bradford Safeguarding Children Board asking them to answer 10 key questions missing from the report.
Mr Timpson said the answers to the "glaring absences" from the review must be made public to "ensure such mistakes will not be repeated in the future".
A Bradford toddler group leader has described her shock at hearing about how Hamzah Khan died, aged just four.
Speaking to Calendar, Christel Nishapati, said she was "amazed that nobody knew he existed".
The children's minister Edward Timpson has said he has "deep concerns" about the serious case review into the death of Hamzah Khan because it "fails to explain sufficiently clearly the actions taken, or not taken, by children's social care".
Four-year-old Hamzah Khan's mummified body was found in a travel cot under a pile of bedding, clothing and shoes, which was riddled with insects in his mother's squalid house.
Last month, his mother Amanda Hutton was sentenced to 15 years in jail for starving him to death last month.
Professor Nick Frost, chair of the Bradford Safeguarding Children Board, has said a serious case review has found four-year-old Hamzah Khan was "let down" by systems.
The SCR is very clear that Hamzah's death could not have been predicted but finds that systems, many of them national systems, let Hamzah down both before and following his death.
Sandra Robertshaw tells Calendar's Claire Ashforth how Hamzah Khan's siblings would visit her shop and were "sweet and polite" children.
The death of four-year-old Hamzah Khan, who was starved to death by his mother "could not have been predicted", a serious case review has found.
But it also concluded that systems "let Hamzah down both before and following his death.
Last month, mother-of-eight Amanda Hutton, 43, was jailed for 15 years after she was found guilty of the manslaughter of her son, whose decomposed body was found in a cot at their home in Bradford, West Yorkshire.
Siobhan Freegard, the founder of Netmums.com - says the reaction amongst her online community to the death of a four-year-old who starved to death was "not again".
Relatives of Hamzah Khan's mother Amanda Hutton - who was today jailed for 15 years, say they blame social services.
