Boohoo has been accused of breaking its promises to treat its suppliers ethically.
Staff at the fast fashion retailer were found to be pressuring suppliers to lower prices, according to an undercover BBC Panorama investigation.
But Boohoo said it has not broken promises or “avoided” addressing historic supply chain failures.

Journalist Emma Lowther said staff at Manchester head office felt “constant pressure to drive prices lower and lower”.
An employee reportedly told him “if you’re not going to get anywhere [with suppliers] then just say you can get it cheaper somewhere else,” adding, “I’m just lying.”
The retailer pledged to reform its practices in 2020 after it was revealed that factory workers making Boohoo clothing were paid less than the minimum wage and treated poorly.
A spokesman said: “As the cost of raw materials, transport and energy began to fall, the group asked its suppliers to reflect this in their prices through discounts of between 1 and 10 per cent, and transferred savings to customers.
