Question to the Home Office:

To ask the Secretary of State for the Home Department, pursuant to the Answer of 3 July 2017 to Question 1480, on human trafficking, on which statistics the Government based its approach to human trafficking and modern slavery; and if she will place a copy of those statistics in the Library.

The Government bases its approach to modern slavery and human trafficking primarily on statistics which cover: potential victims referred to the national referral mechanism and the duty to notify referral process; police recorded crime statistics; and criminal justice statistics. These statistics are collated and published annually in the inter-departmental ministerial group on modern slavery reports available on Gov.uk:

These annual statistics complement a Home Office study conducted in 2014 on the overall scale of modern slavery in the UK, which is also available on Gov.uk:
