The news seemed to come more or less out of the blue. On the London Stock Exchange this morning, Sainsbury's said that Argos boss John Rogers would be stepping down from his role at the end of October, to join international advertising and PR agency WPP. Sainsbury's boss Mike Coupe said that Rogers had "made an outstanding contribution to the business" and, after 14 years of service leaves "without best wishes for the future". For his part, Rogers said the new role was "too good to miss".
