John Fairfax Holdings, Sydney, Australia, has appointed Bob Muscat, formerly chief operating officer of Rupert Murdoch's News Ltd., as chief executive. Mr. Muscat, 48, takes over Aug. 1, replacing Bob Mansfield, who resigned in mid-April following disputes with owner Conrad Black. He will be the tenth CEO in as many years at Fairfax, which publishes the Sydney Morning Herald
, The Age
in Melbourne, the Financial Review
and a stable of regional and Sunday newspapers and national magazines. Mr. Muscat was with News Ltd. for 27 years; his aspirations to succeed CEO Ken Cowley were dealt a blow last year when Mr. Murdoch's elder son Lachlan, 24, was appointed deputy CEO.
