Child trafficking referrals in the UK have hit a record high after rising by 30 per cent in a year, statistics have revealed. The number of children referred to the UK Government's National Referral Mechanism (NRM), which identifies victims of human trafficking, increased to 1,278 in 2016, the highest figure on record, according to the latest figures from the National Crime Agency. More than a third of all potential victims of trafficking were children aged 18 and under, with a majority of children drawn into exploitative labour, including forced criminality. Trafficking covers children moved within the UK, as well as move to the country from abroad. The largest increase was the number of UK national children reported to have been abused in sexual exploitation, which showed a staggering 104.8 per cent rise on the previous year - a rise that it is hoped reflects a growing awareness that child sexual exploitation often manifests in the form of trafficking. Also featuring highly in the figures were countries affected by conflicts ... indicating that children fleeing war and instability are also vulnerable to trafficking and exploitation. A large number of these cases are thought to have travelled ... in the back of lorries facilitated by traffickers or people smugglers - indicating that they can remain at risk of exploitation by the same networks after they have arrived in the UK. Alarmingly, while numbers of potential victims of trafficking increased, positive conclusive decisions - which enable victims to access support - decreased to the lowest point in NRM history.
