James Murdoch is to return to Sky as its chairman, almost four years after he resigned from the company in the wake of the phone-hacking scandal.
The 43-year-old takes up his position after a short stint as chief executive of media giant 21st Century Fox, a role he only took up in July, succeeding his father, Rupert.
Murdoch, the younger son of the 84-year-old media tycoon, has been a director of the pay-TV company since 2003 and previously served as chief executive from 2003 to 2007, before holding the position of chairman from 2007 to 2012.
He bowed to pressure to resign from the role in April that year following the scandal that erupted following phone-hacking involving the Murdoch-owned News of the World.
He takes over as chairman of Sky – which is 39% owned by Fox – from Nick Ferguson, who steps down from the Sky board at the end of July after 12 years as a director.
Sky's group chief executive, Jeremy Darroch, said: "The entire board offers its warmest thanks to Nick for his leadership as chairman and the major contribution he has made to Sky over many years. We're delighted that James Murdoch has agreed to step into the role of chairman.
"James' deep knowledge of the international media industry and his passion for supporting Sky's ongoing success will make an even greater contribution to our business in the future.
"We're excited about 2016 and we start the year with good momentum. With an outstanding set of new initiatives and products for our customers, we are well positioned to deliver further strong growth and returns for shareholders."
Martin Gilbert has been appointed as deputy chairman, while Andrew Sukawaty becomes Sky's senior independent director.
The return of Murdoch will now pose questions as to whether 21st Century Fox will mount a takeover bid for Sky.
Analyst Roddy Davidson, at Shore Capital, said the return of Murdoch was likely to "rekindle speculation regarding 21st Century Fox's plans for its 39 per cent stake".
Campaign group Hacked Off questioned the appointment of Murdoch.
Joint executive director Evan Harris said: "In no normal company, with proper regard to standards of corporate governance, would the board appoint someone under whose management between 2007 and 2012 News International engaged in a cover-up of the extent of phone hacking, and by his failures to prevent it cost the company over £500 million so far."
