Andy Coulson: "I stand by what I've said about those events but when the spokesman needs a spokesman it's time to move on."
Guardian editor-in-chief Alan Rusbridger on Coulson resigning: "This is the result of first class investigative reporting by one  
Guardian  reporter, Nick Davies, sustained over a very long period of  time. From  the moment he revealed the secret payout to Gordon Taylor in  July 2009  it was obvious that Andy Coulson's  position was untenable. But this is  not the end of the story by any  means. There are many outstanding  legal actions, and uncomfortable  questions for others, including the  police."
Robert Peston on his blog: "Not to over-dramatise, this has all the potential for the  newspaper  industry to turn into its version of the MPs' expenses  scandal."
Richard Ingrams in the Independent on Sunday:  "In a world where nothing succeeds like failure, Andy Coulson  has no   reason to fear for his future. He should take heart from the  example of   his labour predecessor Alastair Campbell, who ended up  resigning but  who  is now riding high, publishing books and even  appearing regularly  on  the BBC, an institution which during his career  at Downing Street  he did  more to damage than anyone else in our time."
Sky News political editor Adam Boulton:  "Two important sectors of our society now feel under a great deal of  pressure, beset by plunging fortunes and public esteem: newspapers and  politicians. As they go down they are turning in on each other with  increasing viciousness - politician against journalist, politician  against polititian, journalist against journalist."
Andreas Whittam Smith in the Independent: "But as we have an unwritten  constitution, so we  have writs that are unrecorded. And if it were  spelled out, it would  simply state: never offend the Murdochs. Nobody  will say this in terms  to the Department of Culture that is now handling  media competition  issues. Nobody has written it down for Scotland  Yard's benefit. But  this odious rule has become part of our unofficial  constitution. That  is how bad it is."
Bill Keller, executive editor of the New York Times: "As for our relationship with WikiLeaks, Julian Assange has been heard to boast that he served as a kind of puppet master, recruiting several news organizations, forcing them to work in concert and choreographing their work. This is characteristic braggadocio — or, as my Guardian colleagues would say, bollocks."
Communities and Local Government Select Committee report on the proposed code  of practice on local authority publicity: "We found that there is little hard evidence to support  the view of the  commercial newspaper industry that council  publications are, to any significant extent, competing unfairly with  independent newspapers at present, though there is concern that such  competition may escalate in future."
Leader on cuts to BBC World Service in the Independent: "The World  Service helps to nourish democracy and political  accountability across  the world. Moreover, it produces much  high-quality, impartial, and  authoritative journalism. It exports  British "soft power" and remains an  island of resistance to the global  proliferation of celebrity news. A  relatively small nation such as  Britain may struggle to be heard in the  globalised age. Weakening one  of its strongest international assets is a  mistake."
Peter Sissons in the Daily Mail: "If you want to read one of the few copies of the Daily Mail that find their way into the BBC newsroom, they are difficult to track down, and you would be advised not to make too much of a show of reading them. Wrap them in brown paper or a copy of the Guardian, would be my advice."
