The government asked Baroness Casey to carry out the audit, examining existing data and evidence on the nature and scale of group-based child sexual abuse, in January.

Here are some of its key findings and recommendations.

Lack of reliable data

The report highlights flaws in data collection, which it says means it is not possible to assess the scale of the issue.

It cites the Complex and Organised Child Abuse Dataset which identified around 700 recorded offences of group-based child sexual exploitation in 2023, saying this is the only figure on group-based child sexual exploitation.

The report says this is highly unlikely to reflect the true scale of the issue, given this crime is under-reported and suffers from confusing and inconsistently applied definitions.
