This paper examines the issue of child trafficking in the United Kingdom and of multi-agency responses in tackling it. The UK, as a signatory to the recent trafficking protocols, is required to implement measures to identify and support potential victims of trafficking - via the National Referral Mechanism. Effective support for child victims is reliant on cooperation between agencies. Our regional case-study contends that fragmented agency understandings of protocols and disjointed partnership approaches in service delivery means the trafficking of vulnerable children continues across the region. This paper asserts that child-trafficking in the UK, previously viewed as an isolated localised phenomenon, maybe far more widespread, revealing deficiencies in child protection services for vulnerable children.
