Comcast has secured over 75% of Sky's shares, bringing it closer to finalising the $40 billion takeover of the British pay TV group. 

US cable company Comcast has previously said it hoped the acquisition would complete by the end of October.

Last month Comcast emerged triumphant in the long-running battle for Sky after it beat Rupert Murdoch's Twenty-First Century Fox in an auction. 

Comcast said in a regulatory filing on Thursday that by October 9 - when its acquisition of Twenty-First Century Fox's 39% stake completes - it will hold or have received acceptances in respect of over 75% of Sky's share capital. 

The company said a further announcement will be made in due course.
