Fox News has been an issue for Sky for a while - From the Guardian article
“In the past decade Fox has notched up 22 breaches of its licence and Ofcom’s codes and rules. Of those, seven were against Fox News, with four last year including against a programme which featured a guest who said that Birmingham was a city “where non-Muslims just simply don’t go”.
Fox News was taken off air between 5am and 11pm on election day to avoid any issues with Ofcom”
