Broadcaster Sky and 21st Century Fox have reached agreement on the terms of a takeover deal.
Rupert Murdoch’s 21st Century Fox will pay £11.7bn for the 61% stake it does not already own.
Sky shareholders will receive £10.75 in cash for each share, valuing the company at £18.5bn.
The deal comes amid concerns that Rupert Murdoch, who also owns the Sun and the Times newspapers, will have excessive influence over UK media.
Karen Bradley, the Culture Secretary, will have 10 days to decide whether the Fox bid raises public interest concerns – in this case media plurality. She has the power to ask Ofcom, the media watchdog, to examine the deal.
A number of Sky shareholders, including Standard Life Investments and Jupiter Asset Management, have questioned the independence of the independent directors and its ability to extract a higher price since a possible bid was announced last Friday.
James Murdoch, Rupert Murdoch’s son, is both chairman of Sky and chief executive of Fox.
Thomas Moore, investment director at Standard Life Investments, said this week that the presence of James Murdoch on both boards meant it could not be “an arms-length deal”.
Sky deputy chairman Martin Gilbert, who is also chief executive of Aberdeen Asset Management, which owns a 0.39% stake in the broadcaster, said: “[We] believe 21st Century Fox’s offer at a 40 per cent premium to the undisturbed share price will accelerate and de-risk the delivery of future value for all Sky shareholders. As a result, the independent committee unanimously agreed that we have a proposal that we can put to Sky shareholders and recommend.”

Not all Sky shareholders agree with Martin Gilbert. One told the BBC: “This is a patsy deal. Many of the directors are not really independent and as a group they should be ashamed of themselves.”
The BBC understands that James Murdoch, Rupert Murdoch’s son who is both Sky chairman and chief executive of 21st Century Fox, met with Sky directors earlier this month. He told them: “We are either a buyer or seller of our stake. The status quo is not an option.”
James Murdoch offered a 30% premium to the existing share price on the condition the directors recommended it. After further meetings, that premium was raised to 40%.
But even with that premium, the sale price is roughly what Sky was worth six months ago and many shareholders will feel short-changed.
Chase Carey, the former chief executive of Fox Television and the current co-chief operating officer of 21st Century Fox, is a non-executive director at Sky. While John Nallen, the chief financial officer of 21st Century Fox, is also a non-executive director at Sky.
21st Century Fox plans to take over the remaining stake in Sky through a scheme of arrangement, which means it needs the approval of investors holding 75% of the shares.
Sky has 22 million customers in the UK, Ireland, Italy, Germany and Austria. Mr Murdoch’s son James is both chairman of Sky and chief executive of Fox.
In 2011, Rupert Murdoch abandoned a bid to take full control of Sky in the wake of the phone hacking scandal.
