The chief executive of News Corporation's News International, Tom Mockridge, is leaving the company after only 16 months in the job.
Mr Mockridge took over from Rebekah Brookes, who lost the position because of her involvement in the UK phone hacking scandal.
However, Mr Mockridge has decided to leave the company at the end of the year.
News Corporation's chief executive and chairman, Rupert Murdoch, says Mr Mockridge's decision to step down was entirely his own.
"For nearly 22 years, it has been my pleasure to have Tom Mockridge as a colleague," Mr Murdoch said.
"Whether it was his early days with our newspaper group in Australia, his incredible work building SKY Italia, or his steadfast leadership of News International, Tom has always been a skilled executive and a trusted friend." Mr Mockridge has worked with News Corp since 1991, including stints as the chief executive of Foxtel in the late 1990s and head of the company's New Zealand newspapers, before moving on to Sky Italia and later the role heading News International.
News International is News Corp's UK newspaper operation which publishes the Times, the Sunday Times and the Sun.
