Newspapers groups, victims of phone hacking and other forms of privacy intrusion by the press, and the Metropolitan Police Service have been granted core participant status in the Leveson Inquiry.In his ruling, released today, Lord Justice Leveson explains his decision on the several applications made before him at the Royal Courts of Justice on September 6.Victims represented by lawyers David Sherborne and Jeremy Reed (see full list below) were all accepted as core participants, except for individual HJK (who was granted anonymity in a High Court civil claim) as Lord Justice Leveson would like to learn the individual's identity before considering the application.Former chief executive of News International Rebekah Brooks, private investigator Jonathan Rees (William Rees), and campaigning groups English PEN and Index on Censorship were all refused core participant status for Part 1 of the inquiry.About Mrs Brooks, Lord Justice Leveson wrote: "Although I can understand the reason for this application, in my judgment, it does not pay sufficient attention to the terms of Part I of the Inquiry which is to analyse the way forward in the light of the broad experience (not descending into the detail required by Part 2 of the Inquiry) of the past."Mrs Brooks has very considerable knowledge and experience; I hope and believe that her input into the Inquiry will be of enormous value but, at this stage and in the context of what I am presently required to do, I do not consider that it is necessary or appropriate to designate her as a core participant."The Metropolitan Police Service and Acting Commissioner Tim Godwin have also been named as core participants and will be assisting the inquiry.Guardian News and Media, News International Group Ltd, and Shell Network Ltd (the holding company of the publishing group that includes the Daily Express, the Sunday Express, the Daily Star and the Daily Star Sunday), successfully applied and will be entitled to legal representation during the inquiry.Lord Justice Leveson's ruling read: "Every aspect of Part 1 touches upon the press and its outcome will inevitably be relevant to (if not impact upon) the approach to certain types of news gathering and its dissemination, along with the relationship between the press and the public, the police, potential regulators and politicians."Thus, if the culture and practices of the press require change, the effect will be upon all. In the circumstances, I have no doubt that each of these media groups is entitled to core participant status for each module of this Part."Read Lord Justice Leveson's ruling in full hereIndividuals who have been granted core participants status:Chris Bryant MPTessa Jowell MPDenis MacShane MPThe Rt Hon Lord Prescott of Kingston upon HullJoan SmithChristopher ShipmanTom RowlandMark LewisMark ThomsonGerry McCannKate McCannChristopher JefferiesMax MoseleyBrian PaddickPaul GascoigneDavid MillsSienna MillerHugh GrantBen JacksonCiara ParkesSimon Hughes MPMax CliffordSky AndrewUlrika JonssonMark OatenMichele MilburnAbi TitmussCalum BestClaire WardMary-Ellen FieldGary FlitcroftIan HurstShobna GulatiMike HollingsworthKieron FallonAshvini SharmaTim BlackstoneValatina SemenenkoSally DowlerBob DowlerGemma DowlerSheryl GascoigneGraham ShearJK RowlingJames WatsonMargaret Watson
