Sir: Hasn’t Kevin Hawkins missed the point when he questions why NGOs should be able to influence the behaviour and standards of the big grocery businesses (‘NGOs will never be satisfied,’ 24 August)?

NGOs and their massive support in the UK is something we should be proud of. He asks “who do they represent?” and the answer is hundreds of thousands of supporters without whom many high-profile corporate and commercial injustices would not have been called to account. In the same issue Steve Murrells, the new director of Co-operative Retail, promotes the role the Rochdale Pioneers played in the group’s history: “They changed markets by not accepting the status quo.” Hawkins needs to remember that all those NGO supporters are also consumers. Consumers are who retail and grocery companies are there to serve, and have a right to demand change.
