The UK was shocked to its core in May 2012 when a gang of nine men was convicted of the systematic sexual abuse of disadvantaged teenage girls in the Rochdale area - the crimes including counts of rape, aiding and abetting rape, sexual assault and trafficking girls within the UK for sexual exploitation.

His findings expose how the British justice system is failing to protect children in the 21st century.
It is a scandal that cannot be ignored.
