Rupert Murdoch At Leveson: Will This Be The Most Humble Day Of David Cameron's Life? (SLIDESHOW)

As Rupert Murdoch prepares to appear at the Leveson inquiry, the world is speculating to just what he might reveal.

The media mogul's son James' evidence on Tuesday compromised culture secretary Jeremy Hunt - who is now fighting for his political life.

But with Murdoch senior set to take the stand at 10am on Wednesday to discuss his relationship with prime ministers past and present, we're wondering if any other senior politicians will be in the same situation by lunchtime.

The News Corp owner arrived in Britain at the weekend and came out fighting on Twitter - criticising the government for their latest IMF loan. But he's stayed tight lipped over the past 24 hours.

Check out the best tweets about Murdoch's imminent appearance.
