But in light of the Times report over the weekend, the U.K.'s shadow culture secretary Tom Watson has said he will write to the Competition and Markets Authority (CMA) urging it to turn down 21st Century Fox's £11.7 billion ($15.4 billion) takeover of Sky.
"The latest revelations about Bill O'Reilly are depressingly familiar. They show that 21st Century Fox engaged in a prolonged campaign to cover up allegations of serious sexual harassment by a senior employee instead of investigating the claims and taking action against him," Watson said in a statement emailed to CNBC.
"The fact that Fox handed Mr O'Reilly a lucrative new contract worth $25 million months after he reportedly paid $32 million to settle a claim by a colleague is jaw-dropping. It raises yet more questions about the corporate culture at 21st Century Fox," he added.
Watson compared the O'Reilly allegations to the phone-hacking scandal that caused the 2011 closure of the News of the World, a U.K. tabloid newspaper then owned by News Corp, also run by Murdoch family members.
"Instead of admitting wrongdoing, the Murdoch family's first instinct is to deny it took place and, in many cases, to label those who try to establish the truth as liars or fantasists. It is a pattern that keeps on repeating itself," Watson said.
21st Century Fox owns 39.1 percent of Sky and in December 2016 it bid to take over the remaining proportion. It must go through EU and U.K. approvals — in April, the European Commission green-lit the deal.
However, British Culture Secretary Karen Bradley referred the case in September to the CMA to examine how a takeover would affect media plurality. The CMA will consider whether one person or group has too much influence over public opinion or the political agenda, and its provisional findings are due in December.
