Who’s who in the phone hacking scandal: The casualties so far...

• Andy Coulson - Former News of the World (NOTW) editor and communications chief for Downing Street, Mr Coulson gave up both jobs over phone-hacking allegations. He resigned from his tabloid top job in 2007, saying he deeply regretted that royal editor Clive Goodman and private investigator Glenn Mulcaire had intercepted messages left on royal aides’ phones.

In January this year he left his role as director of communications for David Cameron. Mr Coulson said the drip-drip of claims about illegal eavesdropping under his NOTW editorship was making his job impossible.

• Rebekah Brooks - The chief executive of News International was initially determined to hang on to her job despite the explosive allegations of phone hacking surrounding the company.

But pressure mounted as many people, including the family of murdered schoolgirl Milly Dowler, called for her to go, and the Prime Minister told the Commons that her previous offer to resign should have been accepted. On Friday Ms Brooks sent a message to all News international staff saying her presence was “detracting attention from all our honest endeavours to fix the problems of the past” and she was leaving her role.

• Les Hinton - The chief executive officer of Dow Jones and Co, and publisher of the Wall Street Journal, was a News Corporation veteran. He was head of News International from 1995 to 2007, a period in which the News of the World was allegedly hacking phones.

On Friday night he said that the pain caused to “innocent people” by intrusion into their privacy was “unimaginable” and announced that he had quit.

• Sir Paul Stephenson - The Met chief announced his resignation yesterday after coming under increasing pressure over alleged inappropriate links between the force and News International. Former NOTW executive editor Neil Wallis was employed by the Met as a PR consultant before being arrested for alleged mobile phone interception. Sir Paul had also accepted thousands of pounds-worth of free accommodation at a luxury health spa.

Insisting his integrity is intact, he said: “I have taken this decision as a consequence of the ongoing speculation and accusations relating to the Met’s links with News International at a senior level.”

• John Yates - Today the Scotland Yard assistant commissioner told Metropolitan Police Authority chairman Kit Malthouse that he was standing down. He came under scrutiny over his decision in 2009 that there was no need to reopen the Met’s investigation into phone hacking at the News of the World. He was also on the committee that vetted Mr Wallis for the media adviser contract.

• Tom Crone - He was the senior lawyer who vetted stories for the NOTW for more than 20 years. Mr Crone either left his job as legal manager at News International on July 13, or was asked to leave the role. The media giant would not confirm which.

• Ian Edmondson - Mr Edmondson was sacked as assistant editor (news) at NOTW in January. He had been suspended the previous month over allegations linking him to interception of the voicemails of actors Sienna Miller and Jude Law.

• Clive Goodman - The former NOTW royal editor was sacked in 2007 after being jailed for four months for hacking into messages on royal aides’ phones. He, along with private investigator Glenn Mulcaire, hacked into more than 600 messages on the aides’ mobile phones.
