Campbell said, however, that the testimony was a "disaster" because the MPs had decided he was not Gilligan's main source.
The diary entries covered five days between July 4 and July 15. In his first entry, Campbell writes: "Spoke to H [Hoon], who said that a man had come forward who felt he was probably G's [Gilligan's] source. He had come forward and was being interviewed today.
"GH said his immediate instinct was to throw the book at him but in fact there was a case for trying to get some kind of plea bargaining. Says that he had come forward and he was saying Yes to speaking to AG [Gilligan], yes he said intel [intelligence] went in late but he never said the other stuff. It was double-edged but GH and I agreed it would **** Gilligan if that was his source."
On July 6, Campbell wrote: "GH, like me, wanted to get it out that the source had broken cover to claim AG had misrepresented him."
Blair wanted either Hoon or Campbell to tell the Foreign Affairs Committee - nearing the end of its lengthy investigation into the Iraq invasion - that an unofficial source had come forward.
The entry continues: "His [Blair's] worry was that it could lead to them reopening the inquiry. He wanted, and GH did, to get it to the BBC Governors that we may know who the source was. That he was not a spy, not involved in the WMD dossier and was a WMD expert who advised departments.
"TB [Blair] was fine about that, but backed off speaking to Omand [Sir David Omand, the Cabinet Office security co-ordinator] ... He felt the guy had to be treated properly and interviewed again. I suggested to GH to speak to TB to try to persuade him we should do this."
