A Defence Advisory Notice is something the Government hands down to the media and is essentially a request for the media to not report on something 'in the national interest'. Prince Harry being in Afghanistan is a recent example.
Today, the Defence, Press and Broadcasting Advisory Committee (DPBAC) has made a request to newspaper editors, television and radio broadcasters concerning the soon to be published documents sent between the US State Department and its embassy's around the World.
The DA Notice (standings 01 Military operations & 05 UK Security) is not ordering a blackout of the story and any publication that ignore it is not going to end up in court, but it is a firm reminder that the print and broadcast media should be concerned for disclosing 'information which could damage national security'. It has asked that editors consult with the DPBAC before they publish any information.
The countries said to be the main beneficiaries of the most intensive US diplomatic briefings are the governments of Great Britain, Canada, Israel, Australia, Turkey, Afghanistan, Iraq, Denmark, Italy and Norway.
It seems that whatever is due to be released, it is going to be diplomatic dynamite and hugely embarrassing for the United States.
The Canadian Broadcasting Corporation has closed the comments section on the story on its website.
I expect the British media to largely ignore the DA Notice because on the age of the internet, it is going to be all over blogs and websites before the newspapers hit the newstands.
Nothing stays secret for very long and this DA Notice has been rendered redundant already and the US State Department will be squirming for a long time to come over the exposure of its backroom dealings.
