Russian secret agents have infiltrated Greenpeace and other campaign groups to co-ordinate the war against fracking, it has been alleged.

The Kremlin's distaste for shale gas fracking is not down to a keenly-felt concern for its environmental impact. It is pure economics, born from a desire to keep Europe dependent on gas imports from Moscow.
