Multi-million pound supermarket contracts bought with bribes of luxury holidays and hotel stays. Anna Hill investigates a corruption case involving a supermarket vegetable buyer and one of the UK's biggest potato companies.
Also in the programme - migrants working for less than minimum wage, scammed by employers and forced to live in cramped conditions. These are just some of the day to day experiences gathered by researchers for the Joseph Rowntree Foundation in a new report on forced labour in the UK.
And ahead of the Governments visit to China, Anna Hill tours the John Innes centre in Norfolk to see why it's not just food that is being exported to the Far East.
This programme is presented by Anna Hill and produced in Birmingham by Angela Frain.
