Richard Norton-Taylor put up an artice about The Way of the World book, on Aug 6 2008, at The Guardian's website. On Aug 7 he said he had 'been able to talk' to Nigel Inkster, one of Suskinds main sources for the british side of the story.
Postscript (August 7 2008, 18:30): Since this article was first posted (on August 6 2008), I have been able to talk to Nigel Inkster. After reading the comments attributed to him in Suskind's book, he could only describe them as "inaccurate and misleading". Inkster says:
"Mr Suskind appears to have conflated separate conversations; one about the problems of reading Saddam Hussein's intentions, an issue which is dealt with in the Butler report, and one about Habbush. I made it clear to Mr Suskind that I was in no position to comment on the substance or significance of any dealings with the latter since I had not been privy to the detail of what had taken place, something Mr Suskind has chosen not to mention. And, in any event, I had made it clear to Mr Suskind, when first he approached me, that I would not divulge classified information to which I had had access during my time in government.
"Mr Suskind's characterisation of our meeting is more the stuff of creative fiction than serious reportage, and seeks to make more of it than the circumstances or the content warranted."
