Leveson inquiry into phone hacking: who's appearing on Tuesday

Charlotte Harris Charlotte Harris is a solicitor at Mishcon de Reya, but made her name as a media specialist at Manchester firm JMW. While there, she negotiated a settlement for publicist Max Clifford after his phone was hacked by the News of the World. She went on to represent other victims including football agent Sky Andrew and actor Leslie Ash, and secured a settlement for Ash. Along with the Dowler family's lawyer Mark Lewis, Harris was placed under surveillance by the News of the World, according to private detective Derek Webb. She is likely to give details of her treatment at the hands of the executives who allegedly commissioned Webb during her evidence to the inquiry. Along with Lewis and Sienna Miller's lawyer Mark Thomson, Harris is one of the solicitors who spearheaded a fight to hold the paper to account by pursuing legal actions on behalf of key clients in the high court. The revelations that flowed from those cases helped to open up the first cracks in the "rogue reporter" defence put forward by the News of the World's owner News International, a defence that ultimately crumbled. Chris Atkins London-based film-maker Chris Atkins found himself at the centre of his own tabloid sting in 2009 when he duped several newspapers into running fake stories on celebrities such as singer Avril Lavigne. Atkins' film, Starsuckers, aimed to show that tabloid papers would publish stories with scant regard for their truth. Atkins rose to prominence with an earlier film, Taking Liberties, in 2007 on civil liberties under Tony Blair's government. However, it is his opinions and evidence on the press that will interest the Leveson inquiry. Atkins is likely to rail against the Press Complaints Commission. David Leigh The Guardian's investigations editor, David Leigh, was described by his colleague Nick Davies at the Leveson inquiry as an "artful dodger" journalist who knows how to stay on the right side of the law and the public interest. Leigh has won plaudits for his work that led to the jailing for perjury of Tory defence minister Jonathan Aitken in 1995 and an investigation into secret payments by arms giant BAE. Leigh more recently led the Guardian's collaboration with Julian Assange and the release of redacted US diplomatic cables. Steven Nott Steven Nott, a sales manager from Wales and Vodafone subscriber, claims he tried to raise the alarm about the insecure voicemail system on the company's mobiles phones back in 1999. He went to the authorities and then took his story to the Daily Mirror when Piers Morgan was editor and claims he was told by one of the senior editorial staff that it was a huge story. When they didn't publish it, he went to the Sun. He also informed Scotland Yard, the Home Office and the then Department of Trade and Industry and says he never heard back from any of them.
