[Update at end of post]
Among the right-leaning part of the Fourth Estate, one media magnate stands out in his express dislike of the EU and all it stands for. Rupert Murdoch has been unswervingly opposed for years, and no wonder: all that talk of fair competition is anathema to him. So his papers have veered between scepticism and forthright hostility, and no paper has been more openly hostile to the EU than the Super Soaraway Currant Bun.
The Outers may have thought the Sun would be on their side from the off. Maybe not.
[UPDATE 1 March 1615 hours: what did I tell you? The Guardian has today revealed that Sun editor Tony Gallagher "doesn't yet know whether [the paper] will campaign for Brexit". He hadn't made up his mind? "I don't know. I haven't decided yet".
And then there was this killer observation: "He did not directly address a question about whether he had the 'freedom' to decide the Sun’s line on the referendum – likely to be a reference to the Eurosceptic views of the paper’s owner, Rupert Murdoch – but Gallagher told the Newsworks conference in London on Tuesday that the Sun’s stance on the EU was tailored to its readers".
Gallagher knows all about the "freedom" he enjoys as a Murdoch editor. He will most likely have been reminded of that by Paul Dacre before he left the Mail: Dacre turned down a job offer from Murdoch because he feared he would not be able to "edit with freedom".
This fence-sitting by the Sun points to the Murdochs needing Cameron in place to help them with that 61% of Sky they do not yet own. If they are coming back with another bid, they will hold off having the Sun campaign for Brexit. Tony Gallagher will not have a say in the matter]
