I have also spoken to Evan Harris who has said they will respond, but nothing ever happens.
This particular campaign are using a valid grievance (the hacking of phones) as a mechanism to bring in a substantial restraint on the investigation and reporting of issues involving powerful people and the establishment. The least they could do is to answer questions.
Notes: Letter to Chris Jeffries 3rd December 2012 - no response, Email to John Dickinson-Lilley 18th January 2013 - no response, Email to John Dickinson-Lilley 17th March 2013 (no response, but to be fair this is only today). Also an email to the Media Standards Trust Gordon Ramsay 11th February 2013 - no response. (The Media Standards Trust used to be the same as Hacked Off, but now they have been separated).
If you want me to respond to any comment please either comment only on the past few entries or put something in your comment to make it clear what you are commenting on (the URL would help). Otherwise I will not be able to find the comment quickly and will not respond.
