Jeremy Hunt, the UK culture secretary – and a man known to be sympathetic to the Murdoch media empire – will now decide whether News Corp’s £7.8 billion ($12.5 billion) takeover of BSkyB gets referred to the Competition Commission. Business secretary Vince Cable disqualified himself from the role this afternoon after telling 2 undercover newspaper reporters that he had “declared war on Mr Murdoch and I think we are going to win”. Prime minister David Cameron called Cable’s views on Rupert Murdoch “completely unacceptable”. The BBC has been leaked the full transcript of Cable’s secret taped conversation with the Daily Telegraph reporters. Ofcom is investigating the bid on the grounds of protecting a diversity of voices. It’s not meant to be political. Cable went on: “His whole empire is now under attack… So there are things like that we do in government, that we can’t do… all we can do in opposition is protest.” Robert Peston, the Beeb’s business editor, has been leaked the transcript by a whistleblower unhappy that the Daily Telegraph omitted this part of Cable’s interview in today’s front page splash. News Corp says: “News Corporation is shocked and dismayed by reports of Mr Cable’s comments. They raise serious questions about fairness and due process.” Claire Enders of Enders Analysis, the media analyst who wrote to Cable outlining how the deal would harm media diversity, tells me: “This was a huge mistake on his part. It was my impression that his demeanour had been cool as a cucumber for 6 months. He came across to all parties as not taking a personal interest. This was obviously not sincere.” Earlier today News Corp welcomed the decision by Brussels to give unconditional clearance to its proposed acquisition of the shares in BSkyB that it does not already own.
