Just found this article from The Observer, it’s documenting the correspondence between Thom Yorke and various politicians back in 2006. I wonder whether Thom would meet the Prime Minister now??

“[Blair's advisers] wanted pre-meetings. They wanted to know that I was onside. Also, I was being manoeuvred into a position where if I said the wrong thing post-the meeting, Friends of the Earth would lose their access. Which normally would be called blackmail.’ Yorke flashed a humour-free smile.
