Things may be about to get a bit more tricky for the doughty campaigners at Friends of the Earth. According to the Times' Ben Webster, the Charities Commissioners have taken a dim view of an FoE leaflet that claimed that silica - that's sand to you or me - used in fracking fluid was a known carcinogen.
They were only able to get away with this by claiming that the claims were made by their wholly owned subsidiary FoE Limited, which is not bound by laws about fundraising by deception.
It's anyone's guess what the Commission is going to do about it. They could crack down on campaigning by charities or they could make the subsidiaries abide by the same rules as their parent charities. Everyone is going to watch with interest, including GWPF, who now have their own campaigning arm, albeit one that operates by much better ethical standards than FoE.
