Copa Cogeca is the largest agricultural lobbying group in Europe, claiming to be "the united voice" of 22 million farmers. But a new investigation from Lighthouse Reports suggests the true size of their membership is far smaller than this - and that the group uses its unrivalled influence to block climate and environmental reform, and lobby for industrial farmers at the expense of smallholders.

Bertie spoke to award-winning journalist Thin Lei Win, Lighthouse's Lead Food Systems Reporter, about the story.
