The range was created to “support and inspire women” but is under fire for allegedly exploiting female Sri Lankan workers.

Beyoncé’s clothing range Ivy Park, which is stocked by high street retailers Topshop, has been accused of being made by workers in Sri Lanka earning just 44p an hour, reports The Mirror.

The Lemonade singer’s newly-launched collection for Topshop was created to “support and inspire women” but MAS Holdings – which employs 74,000 workers, 70 percent of them women – has been strongly critcised by Anti-Slavery International after an unnamed seamstress came forward with the claim.

In an interview with The Sun on Sunday, a Topshop spokesperson defended Ivy Park’s “rigorous ethical trading programme” and said “we are proud of our sustained efforts in terms of factory inspections and audits, and our teams work very closely with our suppliers and their factories to ensure compliance.

“We expect our suppliers to meet our code of conduct and we support them in achieving these requirements.”

MAS are not breaking the law, with their poorest workers still getting paid more than Sri Lanka’s legal minimum wage of 13,500 rupees a month.

FACT has approached Beyoncé’s team for comment.
