The UK Government has issued Defence Advisory Notices to editors of UK news outlets in an attempt to hush up the latest bombshell from whistle-blowing web site WikiLeaks.
DA Notices, the last of which was issued in April 2009 after sensitive defence documents were photographed using a telephoto lens in the hand of Assistant Commissioner Bob Quick as he arrived at No 10 Downing Street for a briefing, are requests not to publish, and therefore not legally enforceable.
Which means there are no 'official' repercussions for ignoring the notices, but they are generally adhered to.
The news came to light in two Tweets from WikiLeaks one of which said, "UK Government has issued a "D-notice" warning to all UK news editors, asking to be briefed on upcoming WikiLeaks stories." the follow up pointed out that the notices were "Type 1" which relates to "Military Operations Plans and Capabilities", and "Type 5" which relates to "United Kingdom Security and Intelligence Special Services."
WikiLeaks says the forthcoming mega-leak is seven times larger than the 400,000-document Iraq War Dossier and would redefine global history.
