In the report, Baroness Casey said: “We as a society owe these women a debt.

“They should never have been allowed to have suffered the appalling abuse and violence they went through as children,” she added.

On the question of ethnicity, the report said: “We found that the ethnicity of perpetrators is shied away from and is still not recorded for two-thirds of perpetrators, so we are unable to provide any accurate assessment from the nationally collected data”.

However, it added that at a local level for three police forces – Greater Manchester, South Yorkshire and West Yorkshire – there was enough evidence to show a “disproportionate numbers of men from Asian ethnic backgrounds amongst suspects for group-based child sexual exploitation”.

Cooper said: “Ignoring the issues, not examining and exposing them to the light, allows the criminality and depravity of a minority of men to be used to marginalise whole communities.”

Lady Casey later said the data should be investigated as it was “only helping the bad people” not to give a full picture of the situation, adding: “You’re doing a disservice to two sets of population, the Pakistani and Asian heritage community, and victims.”

The report criticised the “failure” of the authorities to “understand” the nature and scale of the problem to date.

“If we’d got this right years ago – seeing these girls as children raped rather than ‘wayward teenagers’ or collaborators in their abuse, collecting ethnicity data, and acknowledging as a system that we did not do a good enough job – then I doubt we’d be in this place now,” the report stated.

Cooper told the Commons the government would follow all 12 of the report’s recommendations, including suggestions to:

  • Ensure adults who engage in penetrative sex with a child under 16 “face the most serious charge of rape” instead of lesser charges

  • Launch a new national criminal operation overseen by the National Crime Agency (NCA) to tackle grooming gangs and hold a national inquiry that co-ordinates targeted local investigations into abuse

  • Review the criminal convictions of victims of child sexual exploitation and quashing any convictions where the government finds victims were criminalised instead of protected

  • Make the collection of ethnicity and nationality data for all suspects in child sexual abuse and criminal exploitation cases mandatory

  • Commission research into the drivers for group-based child sexual exploitation, including the role of social media, cultural factors and group dynamics

  • Bring in more rigorous standards for the licensing and regulation of taxi drivers following cases of them being used to traffic victims

Cooper said: “To the victims and survivors of sexual exploitation and grooming gangs, on behalf of this and past governments, and the many public authorities who let you down, I want to reiterate an unequivocal apology for the unimaginable pain and suffering that you have suffered, and the failure of our country’s institutions through decades to prevent that harm and keep you safe.”

She added: “Baroness Casey’s first recommendation is we must see children as children. She concludes too many grooming cases have been dropped or downgraded from rape to lesser charges because a 13 to 15-year-old is perceived to have been in love with or had consented to sex with the perpetrator.”

The report is focused on “group-based child exploitation” by grooming gangs, a crime which is defined as involving “multiple perpetrators coercing, manipulating and deceiving children into sex, to create an illusion of consent”.
