Comcast said it held nearly 77 percent of Sky's shares, making its takeover wholly unconditional.

Brian L. Roberts, chairman and CEO of Comcast, said he was pleased to become the majority owner of Sky on Tuesday.

"Led by Jeremy Darroch and his superb team -- now together with Comcast -- our combined global leadership in technology and content paves the way for us to accelerate investment and growth in Sky's brand and premier platforms," he said.

"We are also fully committed to ensuring Sky News' future, maintaining its editorial independence, and preserving its strong track record for trusted, high quality, impartial news."

Sky said the cancellation of its shares was expected to become effective on 7 November.
