21st Century Fox has submitted a new and extended proposal to the Competition and Markets Authority in its on-going attempt to acquire control of Sky.
In letter released by the CMA, Fox proposed to extend its commitment to maintaining Sky News' independence from five to ten years and said the commitment is no longer subject to Fox or a successor owning more than 39.14 per cent of Sky.
"We trust that you will find the revised firewall remedies satisfactory," write Fox.
The CMA announced in January that the £11.7 billion deal should be blocked unless a way is found to prevent the Murdoch family trust from influencing Sky's news output.
The Authority is due to present its final report to Culture Secretary Matt Hancock on 1st May. He has said he will rule on the deal by 14th June.
