The review found agencies were ill-prepared for the scale and complexity of the abuse exposed by the police investigation. It also found issues of culture, ethnicity and identity were a feature in both the victims, who were mostly white, and the perpetrators, who were of Asian heritage, and called for national discussion on this issue.

Internal trafficking of white girls among Pakistani men, mostly in the North of England, is not a new phenomenon. There have been a string of other grooming trials. It is a sad reflection on the impact of political correctness that it is so difficult to talk about the obvious ethnic and cultural links between these crimes. However if we continue to ask the important questions in a spirit of honesty and integrity, we may be able to reach the heart of the matter soon.
