The health worker responsible for gathering the main evidence in the 2012 Rochdale child sex abuse case has told ITV News Ann Coffey's report "doesn't go anywhere" to ensuring it never happens again.
Sara Rowbotham said she had "tried hard to make it clear" to the authorities that children were being sexually exploited but that "nobody did anything meaningful" to stop it.
"Ann Coffey's report doesn't go anywhere to address any of that, it doesn't go anywhere to ensuring that that's never going to happen to anybody again," the whistleblower said.
"She doesn't offer concrete solutions, she doesn't absolutely say we have zero tolerance, it doesn't go anywhere to address the injustice and the absolute terror that happened to those children in Rochdale," she added.
A whistleblower has told ITV News the police were "cherry-picking" which of the Rochdale abuse perpetrators they were going to arrest.
The sexual exploitation of children has become "normal" in some parts of Greater Manchester, according to an independent inquiry.
Children who have been sexually exploited are "blamed for being a victim", a new report suggests.
