Major British retailers including Marks & Spencer, John Lewis and Next are joining forces with law enforcement agencies in a bid to eradicate labour exploitation and modern slavery from the fashion industry, Britain's anti-slavery body said on Tuesday. Six of the country's top fashion brands have vowed to raise awareness to stop worker abuses, protect at-risk and exploited employees, and root out modern slavery from their supply chains, according to the Gangmasters and Labour Abuse Authority (GLAA).
