James Murdoch has been re-elected as Sky chairman after narrowly winning the support of independent shareholders.
At the satellite broadcaster’s annual meeting, 51.5% of independent investors voted for him – up from about 47% last year.
Some investors have complained that Mr Murdoch faces a conflict of interest as both chairman of Sky and chief executive of 21st Century Fox.
He holds those posts while Fox is attempting to take control of Sky.
One investor, Royal London criticised the dual position as “inappropriate”.
However, a Sky spokeswoman said Mr Murdoch was “uniquely well-placed” to be chairman, saying he had “deep knowledge of the global media industry”.
Both 21st Century Fox and News Corp, which owns newspapers including The Times and the Sun, are controlled by his father, media mogul Rupert Murdoch.
Royal London, which owns a stake worth £44m, has raised its concern over James Murdoch’s position.
“Minority shareholders at Sky would be better served by a truly independent chairman,” said Ashley Hamilton Claxton, the firm’s corporate governance manager.
“Independent oversight of the board is particularly important given Fox’s ongoing bid to acquire Sky.”
Three advisory groups – Institutional Shareholder Services, Glass Lewis and Pirc – urged shareholders to vote against Mr Murdoch’s re-election and executive pay at the company.
Fox already owns a 39% stake in Sky, so if that holding is included James Murdoch received the support of 78% of shareholders.
Fox’s bid to buy the 61% stake in Sky which it does not already own is
Telecoms regulator Ofcom earlier has said the deal risks giving the Murdoch family “increased influence” over the UK’s news agenda and political process.
Sky’s latest results showed sales in the three months to 30 September – the first quarter of its financial year – rose 5% to £3.3bn with underlying profits up 11% to £582m.
The company added 160,000 new customers in the quarter, which was up more than 50% than a year earlier.
TV audiences were boosted by the latest season of Game of Thrones where, in the UK, it attracted a record 4.7 million viewers.
Sky shares rose 1.9% to 930p. That is still below the price of £10.75 per share that Fox offered for Sky when it made its bid back in December of last year.
