More than 200 stars including Russell Brand, Sir Ian Mckellen and Dame Maggie Smith have put their names to a campaign to clean up the British press. A long list of celebrities have thrown their support behind the drive from Hacked Off, an organisation fronted by actor Hugh Grant, which calls for tighter regulation of U.K. publications in the aftermath of the phone hacking scandal. Adverts featuring the list, which also includes actor Benedict Cumberbatch, director Alfonso Cuaron and Oscar winner Emma Thompson, ran in a number of British newspapers on Tuesday (18Mar14). The move marks 12 months since the introduction of a Royal Charter to encourage publications to back a new system of self-regulation and the adverts urge more publications to sign up for the scheme. The charter faced a frosty reception from many newspaper editors, who claimed it could leave the press vulnerable to political pressures. It was drafted following an investigation into the phone hacking scandal which first hit headlines in 2011, when it emerged a private investigator employed by a British tabloid newspaper accessed voicemail messages of a number of high profile figures.
