Workers producing clothes in Bangladesh for some of the UK's biggest retailers are being forced to work up to 80 hours a week for as little as 7p an hour, according to a report published today. The study from War on Want claims that conditions in six factories supplying Primark [part of Associated British Foods], Tesco and Asda [part of Wal-Mart] are worse than they were two years ago when the charity carried out its first investigation...Last night Primark said it was committed to ethical sourcing of its clothes and continually audited its suppliers. A spokesman for Asda said it was committed to "doing the right thing" for suppliers. Tesco said it took working conditions in its supply chain "extremely seriously" but criticised War on Want which refused to name the factories in order to protect the workers.
