Sports correspondent Vivek Chaudhary has been promoted to the newly created role of chief sports correspondent after four years reporting on the subject in the paper.
His place is taken by Paul Kelso, who was previously on the newsdesk as a reporter. Kelso was also The Guardian's online sport editor for two years from 1997.
Guardian editor Alan Rusbridger said the appointments meant that 'we will be better able to expose the workings of the industry, particularly at its intersection with business, media, politics and the law'.
Meanwhile Maddy Costa has been made deputy arts editor. She replaces Phil Daoust who has left the paper to concentrate on writing a novel (PRWeek, 2 August).
Costa reports to arts editor Dan Glaister and is expected to work on G2 and the Review sections. She started as a theatre reviewer for London listings and entertainment title Time Out in 1997, before becoming Guardian music reviews editor in 1999.
