Next, the home secretary turns to the rapid review that has just been conducted by Baroness Louise Casey. She examined "the nature, scale and characteristics of gang-based exploitation".
In particular, Baroness Casey was asked to look at "the issue of ethnicity, and the cultural and societal drivers for this type of offending", which had never before been done.
Yvette Cooper described the report's findings as "damning", identifying a "deep-rooted failure to treat children as children", as well as a "continued failure to protect children and teenage girls from rape, from exploitation, and serious violence".
The response from the authorities was "fragmented", with "too little sharing of information", a reliance on "flawed data", as well as "too much denial, too little justice and too many victims still being let down".
The review describes how perpetrators walked free because "no one joined the dots", or the law protected them rather than the victims, information was not shared between local services, and organisations "looked the other way".
Cooper tells MPs: "Baroness Casey found 'blindness, ignorance, prejudice, defensiveness and even good but misdirected intentions' all played a part in this collective failure."
There was also a "failure to gather proper robust national data" on ethnicity, and the report finds "clear evidence of over representation among suspects of Asian and Pakistani-heritage men".
Casey refers to "examples of organisations avoiding the topic altogether for fear of appearing racist or raising community tensions".
Cooper goes on to say that "many of these findings are not new", but "too little has changed".
"We have lost more than a decade. That must end now," Cooper says.
