News Corp Australia has dumped Lisa Muxworthy, the high-profile editor-in-chief of its most-read publication, news.com.au, in one of the biggest overhauls of the Murdoch family’s publishing and broadcast empire in decades.

As first flagged by The Australian Financial Review in April, the restructure is aimed at saving up to $65 million, will likely result in north of 100 redundancies and will leave News Corp with three publishing divisions and a sales unit, elevating key executives and editors while casting others aside.
