to back Cameron. Despite this, there had already been a convergence of interests between the two men over the muting of Britain's communications regulator Ofcom. In August 2008, Cameron accepted free flights to hold private talks and attend private parties with Murdoch on his yacht, the Rosehearty. Cameron declared in the Commons register of interests he accepted a private plane provided by Murdoch's son-in-law, public relations guru Matthew Freud; Cameron did not reveal his talks with Murdoch. The gift of travel in Freud's Gulfstream IV private jet was valued at around £30,000. Other guests attending the "social events" included the then EU trade commissioner Lord Mandelson, the Russian oligarch Oleg Deripaska and co-chairman of NBC Universal Ben Silverman. The Conservatives did not disclose what was discussed. In July 2011, it emerged that Cameron had met key executives of Murdoch's News Corporation a total of 26 times during the 14 months that Cameron had served as Prime Minister up to that point. It was also reported that Murdoch had given Cameron a personal guarantee that there would be no risk attached to hiring Andy Coulson, the former editor of News of the World, as the Conservative Party's communication director in 2007. This was in spite of Coulson having resigned as editor over phone hacking by a reporter. Cameron chose to take Murdoch's advice, despite warnings from Deputy Prime Minister Nick Clegg, Lord Ashdown and The Guardian. Coulson resigned his post in 2011 and was later arrested and questioned on allegations of further criminal activity at the News of the World, specifically the phone hacking scandal. As a result of the subsequent trial, Coulson was sentenced to 18 months in jail. In June 2016, The Sun supported Vote Leave in the United Kingdom European Union membership referendum. Murdoch called the Brexit result "wonderful", comparing the decision to withdraw from the EU to "a prison break….we're out". Anthony Hilton, economics editor for the Evening Standard but describing a period when he interviewed Murdoch for The Guardian, quoted Murdoch as justifying his Euroscepticism with the words "When I go into Downing Street, they do what I say; when I go to Brussels, they take no notice". Murdoch denied saying this later in a letter to the Guardian. With some exceptions, The Sun has generally been supportive of the government of Conservative Prime Minister Boris Johnson. Murdoch and his employees were the media representatives ministers
