Question to the Home Office:

To ask the Secretary of State for the Home Department, what estimate she has made of how many suspected victims of modern slavery were subsequently retrafficked after being referred to the National Referral Mechanism in each of the last three years; and if she will make a statement.

The information requested is not available as it is not routinely recorded as part
of the National Referral Mechanism process. However, the NCA's 'Strategic
Assessment on the Nature and Scale of Human Trafficking in 2013,' which
was based on additional information and intelligence, identified that there
were three cases where a potential victim had experienced a secondary period
of exploitation following recovery during the period 1 January 2013 to
31 December 2013. Similar intelligence assessments were produced in
2011 and 2012 which contained no data relating to the number of potential
victims that may have been re-trafficked.
