At-a-glance: Inquiry's first week

Here are the key points of evidence heard during the first week of the Hutton inquiry into the death of Iraq weapons expert Dr David Kelly:

Dr Kelly's standing

• The inquiry heard that Dr Kelly was the UK's foremost expert on Iraq's weapons of mass destruction
• Since 1996 he had done work for, or advised, a range of government departments, including secret services, and also the United Nations and the CIA

Dr Kelly and the September Iraq dossier

• Dr Kelly wrote the historical part of the dossier but his views were sought on other parts of the document
• He was at an informal meeting on 19 September held by the Defence Intelligence Service which reviewed a version of the dossier produced that day - five days before the final version was published
• Draft versions referred to at the inquiry suggest wording over the claim Iraq could launch weapons of mass destruction within 45 minutes was first included in draft dossier on 10 or 11 September
• It was then weakened in a subsequent draft before being hardened up for the final version
• Two members of the Defence Intelligence Staff formally expressed concern about the language of the dossier - including "probably the most senior and experienced intelligence community working on WMD"
• The main text and executive summary were approved by the Joint Intelligence Committee

Dr Kelly's contacts with the media

• BBC correspondent Andrew Gilligan says he checked with Dr Kelly at the end of their meeting about using some of the scientist's quotes
• Kelly volunteered Alastair Campbell's name to Newsnight's Susan Watts when discussing the dossier, but she considered this "glib" speculation
• In a taped conversation with Ms Watts, Kelly said he could not link Campbell directly to the insertion of the 45-minute claim, but instead pointed the finger at the Number 10 press office and added that Mr Cambell was "synonymous" with it
• Dr Kelly told BBC correspondent Gavin Hewitt that "some spin came into play" on the dossier

The BBC's reporting

• Mr Gilligan admits his language was less than perfect when he said Downing Street "probably knew" the 45-minute claim was "wrong" when it was inserted
• Ms Watts said she felt under pressure from the BBC and complained the corporation had tried to "mould" her reports to corroborate Mr Gilligan's reports
• Mr Gilligan's report went through "proper BBC editorial processes", says BBC news director Richard Sambrook
• Today programme editor Kevin Marsh initially praised Mr Gilligan but later sent an email saying the story had been good investigative journalism "marred by poor reporting" through loose use of language
• Even before the controversial story was broadcast, Dr Kelly told a Foreign Office official he had spoken to Mr Gilligan - this was later relayed to the deputy chief of defence intelligence at the MoD

The government's treatment of Dr Kelly

• Dr Kelly interviewed twice about his media contacts - the second interview conducted at the request of Tony Blair
• The MoD's permanent secretary recommended Dr Kelly not be questioned by the Foreign Affairs Committee, partly as he was not used to the spotlight, but this was overruled by Defence Secretary Geoff Hoon
• Officials briefed Dr Kelly before the MPs' questions and indicated "tricky areas" but they insist they did not tell him how to answer.

Dr Kelly's state of mind

• There was some history of complaints about his pay and his civil service grading
• Said to be "composed" during interviews with Ministry of Defence officials and as he went to face MPs' questions, although concerns were raised that he was feeling the pressure and not handling it well
• Concerned about the publicity surrounding a public hearing in the Commons and nervous about that session
• "Very pleased" when told he would soon be returning to work in Iraq
