21st Century Fox has pledged to guarantee the independence of Sky News in a bid to win approval for the takeover of the channel’s parent company, Sky plc.
The US company has offered to set up an independent editorial board for Sky News, and to continue funding the service for at least five years.
It would also have to disclose any attempt to influence Sky News’ agenda to culture secretary Matthew Hancock.
The “firewall remedies” were revealed in documents published by the Competition and Markets Authority (CMA). The CMA’s final report on the takeover bid will be with Hancock by 1 May.
Sky is already 39%-owned by 21st Century Fox, which is in turn controls News Corporation, publishers of The Times and the Sun.
The US media giant agreed to buy the remaining stake in Sky in 2016, but has been unable to complete the deal thus far, with regulators concerned over too much media control being in the hands of one company.
Meanwhile Walt Disney is pursuing a separate agreement to buy 21st Century Fox's entertainment assets – including its 39% stake in Sky.
Analysts believe if this $50bn deal goes ahead, leaving Disney as Sky’s owner, regulatory issues would disappear.
