This article also seems to be breaching the press embargo: “Nice last issued recommendations on ME in 2007. New final guidance, seen by the Guardian and roughly in line with a draft report published last November, would have abandoned the GET recommendation and also advised that CBT – a talking therapy commonly used to treat anxiety and depression – is not curative for ME.”
Once an embargo has been broken, it is broken. The Guardian would no longer be bound, I think, given that The Times already reported the same thing.
