This document is a dissertation submitted to Anglia Ruskin University by Tom Martlew exploring the practicalities of enforcing the UK's Modern Slavery Act. It examines a case study of four members of a Latvian organized crime group convicted in 2016 for offenses related to the exploitation of migrant workers in Wisbech, UK. Through interviews with police and local council practitioners, the study found that while overcoming challenges in identifying and investigating this complex crime, the fundamental obstacle to obtaining convictions is defining and evidencing where labor exploitation becomes forced labor under the Act.
