This column hereby promises maximum scrutiny of the private life of Rebekah Wade

The appointment of Rebekah Wade as the editor of the Sun has given rise to much baseless speculation. It has been suggested that she may swing the paper behind the euro. We are told she may ditch Page Three girls, to whom she is said to have a feminist aversion. She is, says my esteemed colleague Roy Campbell-Greenslade in the Guardian, a former young Tory who may be ‘ready to cut the umbilical cord with Downing Street’ and support Iain Duncan Smith or whoever may succeed him.

All these theories ignore a simple fact. It is Rupert Murdoch, not Rebekah Wade, who will determine the editorial policy and future political allegiances of the Sun. I don’t doubt that she will have a say at the margins, but she is not going to be allowed to do what Mr Murdoch does not want her to. If Mr Murdoch remains against the euro, so does the Sun.
