A scathing opinion column on corporate-funded think tanks work such as the International Policy Network and the Demos Institute cited Blundell dismissing them as "wonk whores". He says: "Global companies are buying up think-tanks left, right and centre. Large cheques come attached to particular policy recommendations and senior corporate types sit on committees ready to ‘candle-snuff’ dangerous ideas," Paul Staines reported in The Times. In a subsequent letter to the editor, Blundell, who is a trustee of IPN, stated that "the purchase by companies of 'particular policy recommendations' from groups pretending to be independent think-tanks is disgraceful. That is why International Policy Network, a UK charity of which I am a trustee, has a strict policy of not allowing its donors to influence the conclusions of its policy work, and a strict conflict of interest policy."
