Alastair Campbell used to say that no story lasted for more than forty eight hours. I don't know what he thinks of the phone hacking saga's marathon stay at the top of TV running orders but plainly we're in for the long haul, as the judicial inquiries play out in parallel with the two police probes - and whatever criminal proceedings come out of them.
So here's my list of tweeters who are particularly good to follow on this story, which comes with the usual caveat that no twitter list can be definitive...
Editor Alan Rusbridger; and his deputy Ian Katz. Guardian Politics is also useful, Patrick Wintour is the political editor. There's also media editor Dan Sabbagh, and reporter Josh Halliday. Web editor Jonathan Haynes is well worth your clickage, while the Sultans of this story are investigations editor David Leigh and his special correspondent Nick Davies - who gets a lot of the credit for keeping on keeping on.
Providing not so much news-tweets so much as pungent tabloid comment via both her feed and her blog, Fleet Street Fox is essential. But she has just got a well deserved book deal, so we might be hearing less from her. Guido Fawkes is also key, as is Dizzy Thinks. Danny Finkelstein of the Times often makes useful observations. Keir Simmons of ITV works hard on the story as does Andy Davies at Channel Four. I'm not quite sure who Bernard Cole is or who he works for, but he says interesting things on this issue. The story is now across the Atlantic and Michael Wolff, a contributing editor at Vanity Fair is a great follow. My colleague Robert Peston continues to break stories on phone hacking, as does the BBC's Jon Manel. The view from inside Wapping is represented by, among others, the Sun's Political Team.
In no particular order, I follow Tom Watson, the Labour MP for West Bromwich East who has become the Murdoch's tormenter in chief..Louise Mensch and Therese Coffey are his colleagues on the Culture and Media select committee. She has just had to apologise to the ubiquitous Piers Morgan for misquoting an article about phone hacking. Jeremy Hunt has a twitter feed, but he's been quiet of late. His department, The DCMS tweets more frequently as does Number 10. Others worth a look are Sara Payne's Phoenix Chief Advocates and Hayley Barlow, the publicist who was until recently working for the News of the World.
Not exhaustive, and I promise I'll update this entry as the saga unfolds.
