Richard Caseby may no longer be managing editor of The Sun but he is still securing apologies from The Guardian in his new job as director of strategic communications at the Department of Work and Pensions.

In his previous job Caseby persuaded The Guardian to publish a lengthy correction when it amended 37 articles which wrongly stated that News of the World journalists deleted voicemail messages providing “false hope” that missing school girl Milly Dowler was alive.

Today The Guardian apologised over a Polly Toynbee comment piece on 11 April which said: “Forget Civil Service factual information: Duncan Smith has just hired a Murdoch managing editor from the Sun and the Sunday Times. Perhaps he helps hone Duncan Smith's terminology inexactitudes."
