Paul Staines ("Guido Fawkes") has been praised and criticised for publishing the leaked Motorman files relating to News International this week. These files appear to show the names of journalists who asked private investigator Steve Whittamore for information on hundreds of people, most of them not public names, along with the names of those people.
