DRC: Mining giant Glencore accused in child labour and acid dumping row

Glencore, the commodity and mining firm worth £27bn, stands accused in the Democratic Republic of the Congo of dumping raw acid and profiting from children working 150ft underground. The revelations come as the notoriously secretive Swiss-based company, which floated on the London Stock Exchange last year, seeks to merge with mining firm Xstrata in a £50bn-plus deal.
