Beyoncé’s new range of women’s sportswear is made using sweat shop labourers who earn as little as £4.30 a day, it has been reported. The American pop star’s Ivy Park gym gear is sold by Top Shop, the high street fashion retailer owned by Sir Philip Green. A Sunday newspaper reported the clothing range – which Beyoncé said she hopes will “support and inspire women” – is made by Sri Lankan seamstresses some of whom earn £4.30 a day. Workers are paid more than the legal minimum wage but campaigners described the labour as "form of sweat shop slavery". A Topshop representative said that the Ivy Park has a rigourous ethical trading standards and that they expect suppliers to be able to meet their code of conduct.
