Five witnesses have given evidence so far on the first day of Lord Hutton's inquiry into the death of Dr David Kelly. Here are the key points.
Evidence from Terence Taylor, president and executive director, International Institute of Strategic Studies
Dr Kelly played a key role in tracking down Iraq's biological weapons programme, Terence Taylor, his friend and colleague said.
Dr Kelly's work in Iraq was "remarkably successful", said Mr Taylor,
The scientist was in a "normal state of mind" a few weeks before his death, Mr Taylor said.
He had had some "negative thoughts" about the consultancy arrangements of colleagues, but this was not said in a "very strong manner", said Mr Taylor.
Evidence from Richard Hatfield, personnel director, Ministry of Defence
Dr Kelly regularly briefed journalists - part of his job was to communicate "Iraq issues to
This was "effectively part of his job description" said Mr Hatfield.
He was referred to as "the expert of choice" on Iraq issues in one document for the media.
A MoD document referred to him having had meetings with Andrew Gilligan, who broke the original BBC story about Iraq's weapons, Nick Rufford of the Sunday Times, Alex Nicoll of the Financial Times and Jane Corbin and Tom Mangold of the BBC.
Dr Kelly was not authorised to comment on or disclose classified information or to discuss "politically controversial issues".
Mr Hatfield said he "strayed" from this in his meetings with Mr Gilligan

The scientist was unhappy with his civil service grading, which fully cleared him to see secret intelligence material on a "need to know basis".
The MoD agreed to confirm Dr Kelly's name as a possible source for the BBC story if the correct name was put to them, said Mr Hatfield.
He said it was expected that Dr Kelly would be giving evidence to at least one
parliamentary inquiry, when his name would become public.
Evidence from Patrick Lamb, deputy head of the Foreign and Commonwealth Office counter-proliferation department
Mr Lamb said Dr Kelly only contributed to the historical part of the Iraq dossier produced by the government last September.
He never attended any Cabinet Office meetings about the dossier, said Mr Lamb.
Mr Lamb said he didn't know how many drafts there were of the dossier.
Evidence from Deputy Chief of Defence Intelligence Martin Howard
Two members of the Defence Intelligence Staff (DIS) had written
formally expressing concern about the way intelligence was presented in the
dossier, said Mr Howard.
They were concerned about the use of language rather than the actual content.
The inquiry was shown an e-mail by a defence intelligence services official which said Dr Kelly had had doubts about an assertion that the UN weapon inspectors had been
unable to account for 20 tonnes of biological growth agents.
The DIS officer wrote that he had been told by Dr Kelly: "The existing
wording is not wrong but it has lost (sic) of spin on it".
Evidence from Julian Miller, chief of the assessment staff in the Cabinet Office
Mr Miller said he was not aware of unhappiness among intelligence service personnel about the September 2002 dossier
He said his department's view was that it was right to use the 45-minutes claim in the dossier.
He said the inclusion of the claim was not made on the orders of Downing Street
He said the claim was not inaccurate
Lord Hutton's opening statement
Lord Hutton disclosed that four electrocardiogram pads discovered on Dr
Kelly's body - which he had mentioned at a preliminary hearing - had been left
by an ambulance crew.
