I soon realised that the greens and their industrial and bureaucratic allies are used to getting things their own way. I received more death threats in a few months at Defra than I ever did as secretary of state for Northern Ireland. My home address was circulated worldwide with an incitement to trash it; I was burnt in effigy by Greenpeace as I was recovering from an operation to save my eyesight. But I did not set out to be popular with lobbyists and I never forgot that they were not the people I was elected to serve.
