Workers rights groups are calling on retailers to use a legally binding deal to improve safety for clothes factory workers in Bangladesh as a blueprint for tackling similar problems elsewhere.

It comes amid evidence that workers in Pakistan and China face greater workplace risks than those in Bangladesh. [refers to Primark, Marks & Spencer, H&M]
