She resigns on the day that the FBI announce that they are investigating whether there was hacking into the phones of victims and families of 9/11?
The FBI would not be starting such an emotive investigation if they did not already have some basic evidence.
I'm guessing this is the bigger thing that was alluded to when she told the NOW staff that they would understand in due course why the paper had to close.
I wouldn't be surprised if within 12 months she is being extradited to America to face criminal charges.
This could possibly end up being the end of Murdoch as well, given the sensitivity of anything to do with 9/11. The relationship between News Corp and the Republicans is not parasitic, it is symbiotic. If this turns out to be true, the republican party will do everything it can to distance itself from News Corp given next years elections. Murdoch not survive that.
