Leveson phone-hacking inquiry: JK Rowling is among the 46 initial 'core participants'.
Harry Potter author JK Rowling, who famously guards her privacy, is one of a number of prominent public figures expected to give evidence to Lord Justice Leveson's judicial inquiry into phone hacking and media ethics and practices.
Rowling is one of 46 celebrities, politicians, sportsmen, other public figures, and members of the public who believe they have been the victims of media intrusion granted "core participant" status in the inquiry by Leveson on Wednesday.
This will mean Rowling and other core participants can give evidence personally, or via a lawyer, on her experience of alleged media intrusion to the inquiry, which begins in October at London's Royal Courts of Justice.
The Harry Potter author has previously expressed her displeasure with the press. In May 2008, she won a legal battle to secure the privacy of her children after photographs were published in the Sunday Express of her young son as he was wheeled down an Edinburgh street in a push-chair.
Others on the list including Anne Diamond's former husband, Mike Hollingsworth; former nurse turned model and TV presenter Abi Titmuss; Sheryl Gascoigne; and Mark Oaten, the former MP who had to pull out of the Liberal Democrat leadership race after tabloid revelations about his sex life.
The parents of murder victim Diane Watson also in Leveson's initial core participants list, along with the parents and sister of teenage murder victim Milly Dowler, and the parents of Madeleine McCann. The son of mass murderer Harold Shipman is also on the list.
Christopher Jefferies, arrested on suspicion of murdering Joanna Yeates in December but released without charge, has also been granted core participant status. He subsequently sued several newspapers successfully for libel.
Several celebrities who have allegedly had their phones hacked, including Hugh Grant, Sienna Miller and Calum Best, are among the 46 named on Leveson's list of core participants.
MPs Chris Bryant, Tessa Jowell, Denis MacShane, Simon Hughes, and former Labour deputy leader Lord Prescott also feature, along with a smattering of sports stars including jockey Kieron Fallon and former Premiership footballer Garry Flitcroft.
Rebekah Brooks, former News International chief executive and editor of the News of the World and the Sun, has been denied her application to become a core participant as she no longer works for the Murdoch company, but she will be able to give evidence as a witness. She has appointed a lawyer to act on her behalf who will under the rules of the inquiry will be allowed to apply to ask questions.
Jonathan Rees, a private investigator who was at one stage employed by the News of the World, also applied to be a core participant, arguing that there "might be significant criticism of him".
However, Rees was also denied the status of core participant on the grounds that he was not of significant enough interest to the first module of the inquiry. This will focus on the relationship between the press and the public and extends not merely to the allegations of phone hacking but also to other potentially illegal or unethical behaviour.
News International, owner of the paper at the centre of the phone-hacking scandal, the now defunct News of the World, the Sunday Times, the Times and the Sun, has been given core participant status as expected, as has Guardian News & Media, the owner of the Guardian, which has published a series of revelations on phone hacking over the past two years.
Daily Mail publisher Associated Newspapers and Richard Desmond's Northern & Shell, owner of the Daily Express, the Sunday Express and the Daily Star, will also be core participants.
English PEN, a writers' freedom association, and Index on Censorship were also denied core participant status.
Barrister David Sherborne, who is representing a group of victims suing the News of the World alleged phone hacking, including Hugh Grant and Jemima Khan, had applied to represent 14 people who either believe their voicemail was intercepted or claimed to have their privacy invaded by the press.
However, Leveson said he was not prepared to give core participant status to those who could not be named.
Leveson has also decided the Metropolitan police can be a core participant.
