My hon. Friend is making a very powerful and, actually, a very upsetting speech. In particular, she mentioned Kenyan bean farmers, and a lot of us thought we were doing some good when we bought those beans. Does she agree that, along with the supermarkets, we need to look at the wider catering industry, food processing and cafés, which often like to portray themselves as fair and good trading environments? Does she also agree that we need some system that enforces such regulations across the sector?
