Clothing workers making fashions for leading retailers such as TopShop are being forced to work in freezing temperatures and dangerous conditions in the heart of London, a newspaper claimed on Tuesday.

The Evening Standard said its reporters discovered the immigrant labourers working in "appalling" conditions for poor pay in the East End. Some were making blue jackets for sale in TopShop with a retail price of £50.

Today, Arcadia chief Philip Green promised the garments would be destroyed rather than go on sale and said the supplier concerned would lose his contract with the fashion giant.

"The supplier will not be used again as he has broken the code of conduct with us. We are pleased this has been brought to our attention," Mr Green told the paper.
