Slaves forced to work for no pay for years at a time under threat of extreme violence are being used to supply seafood sold by major US, British and other European retailers including Walmart, Carrefour, Costco, Tesco, Morrisons, the Co-operative, Aldi and Iceland, the Guardian has revealed.
A six-month investigation established that large numbers of men are bought, sold and held against their will on fishing boats off Thailand and are integral to the production of prawns sold in major supermarkets in the UK and US.
Journalists Kate Hodal and Chris Kelly who worked on the investigation and Steve Trent from the Environmental Justice Foundation will answer your questions between 12-1pm GMT Wednesday 11 June.
