Rebekah Brooks has resigned from News International. After all the events of the past few days – the News of the World axed, 200 staff made redundant, Rupert Murdoch mounting a personal defence of her, David Cameron announcing a judge-led inquiry into the phone hacking allegations – this is the most  unexpected.

It has been generally assumed that the reason the Murdochs shed the News of the World and dropped the BskyB bid was to keep Brooks in her post. She was what stood between them and the public’s wrath. She was editor of the paper at the time of the hacking allegations. If she took responsibility and went, there would be nothing stopping MPs, the FBI and the public in general coming for them.

But now she’s gone. All the furore yesterday about whether or not the Murdochs could be compelled to give evidence to the culture, media and sport select committee on Tuesday is now somewhat overshadowed. In her statement, she says:

“My resignation makes it possible for me to have the freedom and the time to give my full cooperation to all the current and future inquiries, the police investigations and the CMS appearance.”

There are two possibilities – either what Brooks is going to have to say to MPs on Tuesday is so terrible that if she were still part of News International, the damage to the company would render it definitely beyond any kind of resurrection, however hard Edelman tries. Or this is another ploy by the Murdochs to diminish the significance of their own appearance. Naturally, all eyes will now be on what the ex-News International employee has to say to the committee now she’s no longer sheltered inside the Murdoch empire.
