It's hard to believe, but at 4pm BST today it will be exactly a year since Nick Davies and Amelia Hill published online a leak from Operation Weeting, the newly recreated (third) investigation into phone hacking, and revealed that the News of the World had hacked the phone of a missing 13 year old schoolgirl, who was found dead six months later, murdered by Levi Bellfield.

That headline changed the political scene here in the UK. Within days the News of the World had closed, and New Corp were forced to withdraw their takeover bid for Britain's most lucrative broadcaster, BSkyB. Within two weeks James and Rupert Murdoch were summoned to appear before a Parliamentary select committee, and David Cameron was forced to set up the Leveson Inquiry.
