That leads to the obvious question: who is the source for this disclosure? Snowden this morning said he wants it to be clear that he was not the source for the Independent, stating:

I have never spoken with, worked with, or provided any journalistic materials to the Independent. The journalists I have worked with have, at my request, been judicious and careful in ensuring that the only things disclosed are what the public should know but that does not place any person in danger. People at all levels of society up to and including the President of the United States have recognized the contribution of these careful disclosures to a necessary public debate, and we are proud of this record.

“It appears that the UK government is now seeking to create an appearance that the Guardian and Washington Post’s disclosures are harmful, and they are doing so by intentionally leaking harmful information to The Independent and attributing it to others. The UK government should explain the reasoning behind this decision to disclose information that, were it released by a private citizen, they would argue is a criminal act.”
