( CNN ) -- When Rupert Murdoch fired off a tweet Saturday about some `` scumbag celebrities '' he did n't mean `` any particular people , '' the News Corp boss later tweeted . `` I never referred to any particular people , just some 'dodgy ' self promoting celebrities , '' he said , adding the words : `` Repeat apology for language . '' Murdoch found himself in trouble on Twitter over the weekend for apparently referring to Welsh singer Charlotte Church , actor Hugh Grant and television presenter Jacqui Hames as `` scumbags '' after they met with British Prime Minister David Cameron to discuss the potential reform of Britain 's media laws . It 's not clear whether Grant attended the meeting , but on October 9 British media reported that Church and Hames met Cameron during the Conservative Party conference in Birmingham , England . The meeting came weeks before the Leveson Inquiry is due to report its findings on the culture , practices and ethics of the British press and its relationship with the public , police and politicians . The inquiry heard from Murdoch and former British Prime Ministers , Tony Blair and Gordon Brown , along with celebrities , sports stars and even the families of murder victims who claimed that their phones had been hacked by employees of the now defunct , Murdoch-owned newspaper , `` News of the World '' ( NOTW ) . On Saturday , the media baron tweeted : . The missive prompted this retort from Church : . Hames , a former detective-turned TV presenter who fronted the British crime-fighting program Crimewatch , also demanded an apology , after earlier tweeting : `` I 've been called worse , but admittedly not by CEO of large multinational corp. '' Both women , along with actor Hugh Grant -- who is not on Twitter -- have been vocal supporters of Hacked Off , a pressure group that 's fighting for `` a better press that is answerable to the public it is supposed to serve , '' according to its website . They were among 60 signatories to an open letter on October 6 that called on Cameron to keep an open mind when considering Leveson 's recommendations on press reforms . It followed British media reports that suggested the British prime minister might be leaning towards self-regulation . Actor Grant told the BBC 's `` The Andrew Marr Show '' on October 7 that campaigners had been concerned to hear `` weird rumblings '' from government ministers . `` We get these odd articles in The Times saying the government ... close sources or reliable sources at No . 10 say the government has already decided not even to listen to Leveson before it 's published and to go with more , yet more self-regulation of the press , '' Grant said . Cameron appeared on the same program to say he did n't want to preempt Leveson 's recommendations , but added , `` we do n't want heavy-handed state intervention . We 've got to have a free press . '' Lord Justice Leveson is expected to hand down his findings in early November . Months of evidence included the high-profile grilling of Murdoch , who told the inquiry he did n't believe in journalists using phone hacking or private detectives , calling it `` a lazy way of reporters doing their job . '' He painted News Corporation , which owns the Sun and the Times in London , as well as The Wall Street Journal , New York Post and Fox News , as a victim of the cover-up . `` Someone took charge of a cover-up , which we were victim to and I regret , '' he said . Last year , at one of two UK parliamentary inquiries into the hacking scandal , Murdoch said his appearance was `` the most humble day of my life . '' A number of former News Corp. staff have been arrested and charged with conspiracy to intercept communications including former NOTW editor Rebekah Brooks who 's scheduled to face trial next year . The phone hacking scandal erupted and drew international condemnation when it was alleged that NOTW reporters had hacked the mobile phone of Milly Dowler , a 13-year-old schoolgirl who was abducted in March 2002 and found dead six months later . During her disappearance , NOTW reporters were said to have illegally accessed the teenager 's voicemail , a move her parents said had given them `` false hope '' that their daughter was alive . However , a police investigation found that `` it is not possible to state with any certainty whether Milly 's voicemails were or were not deleted . '' Despite the lack of conclusive evidence in the Dowler case , dozens of other high-profile victims alleged that private information that could have only come from their mobile phones had been publicly divulged by the British press . In comments published Saturday , Grant said the soon-to-be released Leveson report would be a `` defining '' moment for the British public . `` No-one wants a state-run media , but what we have had for thirty-odd years is a media-run state , '' he wrote .
