Radiohead's Thom Yorke has claimed in a new interview that advisers to former Prime Minister Tony Blair "tried to blackmail" him when he was the spokesman for climate change campaign The Big Ask in 2003. At the time of the campaign, part of environmental organization Friends of the Earth, the Radiohead singer was asking politicians to acknowledge climate change. Yorke told Télérama "It got into this big fight ... [They said,] 'If you don't agree to meet the prime minister, Friends of the Earth will be denied all access to him. Because of the Iraq war, I didn't want to do it. I felt it was morally unacceptable for me to be photographed with Blair."
