Where did the narratives about David Kelly's death being suicide and there being, in effect, a single source for Andrew Gilligan originate?
Interestingly, both lines of thinking can be traced back to Tom Mangold on 18th and 19th July 2003.
In an article published on 19th July 2003, Kelly 'believed he was major source' for Gilligan?s story, Tom Mangold is quoted as stating "He felt he was Gilligan's major source.".
Despite the "headline" quote, much of the article casts doubt on Mangold's speculation.
Similarly, we find in an article (Kelly 'didn't want to live') in the Sun published on 19th July 2003 Mangold is quoted as saying that Janice Kelly stated the following to him: "“She didn’t use the word depressed, but she said he was very unhappy and this was really not the kind of world he wanted to live in."
The Guardian in an article posted on 18th July 2003, Body matches Kelly's description, quotes Mangold as having stated the same words to ITV News (presumably earlier on 18th July 2003).
I don't pretend that Tom Mangold is the only source from which these matters might be traced but I find it very interesting that he is so active in the media propagating these two ideas so soon after David Kelly's death.
By early afternoon on 18th July 2003 (perhaps even before Dr. Nicholas Hunt began to examine David Kelly's body) Tom Mangold is briefing that it was suicide.
One has to ask what motives he might have for briefing the media in such a way before the facts were known.
