There are an estimated 136,000 people living on conditions of modern slavery in the United Kingdom (Global Slavery Index 2018). According to the 2017 annual figures provided by the National Crime Agency, 5, 145 potential victims of modern slavery were referred through the National Referral Mechanism in 2017, of whom 2,454 were female, 2688 were male and 3 were transgender, with 41% of all referrals being children at the time of exploitation. People are subjected to slavery in the UK in the form of domestic servitude, labour exploitation, organ harvesting and sexual exploitation, with the largest number of potential victims originating from Albania, China, Vietnam and Nigeria. This data however does not consider the unknown numbers of victims that are not reported. Grace was trafficked from Nigeria to the UK into forced prostitution by a local woman who used the traditional African belief of Juju to threaten her. Eventually she escaped and told the police what happened but her trafficker and the woman that sold her fled the UK.
