Oxfam has published a report on Marks and Spencer’s food and footwear supply chain, after being asked by the brand to act as a "critical friend" and conduct a gap analysis of its supply chain.

Through our participation, we hope to promote some of the good practice of our members. But we will also highlight that much more still needs to be done to improve working conditions in global supply chains.

The government will continue to rely heavily on voluntary principles, guidance and codes of conduct, the promotion of good practice, and an expectation that the private sector will itself do more to ensure respect for labour rights in its supply chains.

Martina Macpherson tells us about the growing importance investors place on social factors and impact.
