Here are the key points from day seven of the Hutton inquiry into the death of Dr David Kelly.
Sir Kevin Tebbit
The Ministry of Defence's permanent secretary was asked if the MoD was a leaky department.
He replied: "Yes, I don't enjoy this experience but it is a large department with three armed forces, three armed services and there have, from time to time..."
The MoD's deputy chief of defence intelligence, Martin Howard, told Sir Kevin on 18 June that Dr Kelly had admitted speaking to Andrew Gilligan.
Sir Kevin said he agreed that there should be a discussion with Dr Kelly to establish what contacts were going on and asked MoD personnel director Richard Hatfield to interview him.
He made that choice because he wanted the situation to be appraised "as coolly as possible and not by people who were themselves caught up in the intense political issues of the moment".
Sir Kevin told Defence Secretary Geoff Hoon on 3 July about developments but without naming Dr Kelly.
Mr Hoon said he was concerned that the government did not appear as though they were covering things up by not naming Dr Kelly.
Sir Kevin said that Dr Kelly would have been aware his name might come out.
Sir Kevin wrote to Sir David Omand - who is responsible for security and intelligence matters at the Cabinet Office - reporting that an official had come forward.
He suggested three possibilities over the leak: that Mr Gilligan had embellished what he had been told by Dr Kelly, that the source was someone other than Dr Kelly or that there was more than one source.
At this stage Sir Kevin said he was trying to control the outing of Dr Kelly out of consideration for the weapons expert.
He said he may have named Dr Kelly to Sir David during a phone conversation and that maybe how Number 10 came to hear of it.
It was at about this time Sir Kevin was told of Tony Blair's interest by Sir David.
There was an implication that the prime minister wanted something done about naming Dr Kelly, said Sir Kevin.
Sir Kevin attended a meeting with the prime minister and Sir David, among others, who he warned that Dr Kelly was not "some windfall bonus" for the government but an awkward development.
At the meeting it was agreed that Dr Kelly be interviewed again to iron out any remaining discrepancies.
Sir Kevin said there was no question Dr Kelly was under duress.
Sir Kevin said he did not know if Dr Kelly had received a "security style" interview but added that he got as thorough an examination as possible.
Sir Kevin said he "acquiesced" with Mr Hoon's decision to put Dr Kelly in front of the FAC: "That was the secretary of state's prerogative, and I accepted that."
Sir Kevin said he talked to Mr Howard on 14 July about whether Dr Kelly was feeling under stress.
He said he felt a "deep sense of responsibility, not of culpability" for someone who was a member of his staff.
But the government's integrity was at stake "and in those circumstances we have to weigh that against individual considerations".
Godric Smith's evidence
Prime minister's official spokesman Mr Smith said the Iraq dossier was "clearly an issue which was being overseen on the presentation side by Alastair Campbell".
On 4 July Mr Smith said he was told by Alastair Campbell that someone had come forward who could be Andrew Gilligan's source and that the matter would be handled by the MoD.
Mr Smith said on 7 July he took part in a discussion in which Alastair Campbell floated the idea of leaking to a newspaper the fact that an official had volunteered details of his links with Mr Gilligan.
"I reflected on what I had heard and thought it was a bad idea," said Mr Smith.
Mr Smith said he had no part in revealing Dr Kelly's name on 9 July.
He said that he thought Dr Kelly was unwise to have the kind of contacts he had with journalists but that he had probably been misrepresented.
Tom Kelly's evidence
Mr Kelly, another of Mr Blair's official spokesmen, said he was someone used as a sounding board when it came to the dossier rather than being a substantive contributor.
Mr Kelly said he put out the rebuttal to Andrew Gilligan's story after being told that by Alastair Campbell it contained assertions that were not true.
Mr Kelly said both he and Mr Smith had a conversation with the Mr Campbell in which they told him it was a bad idea to leak the fact that an official had come forward admitting he had spoken to Mr Gilligan.
Mr Kelly was been asked about his use of the term "game of chicken" to refer to the dispute with the BBC.
He said it was not language he would normally use but he was talking to a close colleague.
He insisted that he did not regard the matter as a game but he believed a private a resolution to the row could not now be reached.
Mr Kelly was asked about his comments describing Dr Kelly as a "Walter Mitty character".
He said the remarks were made in a background briefing that he had understood would not be quoted.
"It was a mistake ... I unreservedly apologise to the Kelly family that words of mine intruded into their grief at that time."
Mr Kelly said his remarks did not reflect the mindset at Number 10.
