It seems everything has gone toxic in the world of branding this week. You cannot move in PR Week (12 June) without stories of “contamination”. Hazel Blears’ ex-special adviser Paul Richards has warned that Labour’s brand is in “real danger of contamination”. Columnist Alex Aiken writes that “detoxifying a brand is a long-term operation” and editor Danny Rogers talks of “David Cameron’s ‘decontaminated Conservatives’.” Looks like we’re all going to need thick gloves and face masks from now on.
