UNICEF has identified a loophole in the British legal code that allows children to be smuggled into the United Kingdom for non-sexual forced labour. The U.N. agency, which plans to publish a major study on child trafficking this summer, says that although the British government has made the smuggling of children for prostitution an offence punishable by up to 14 years in jail, those who traffic children for labour in sweatshops or private houses face no such penalty.
