It's official: Blair's government set out to deceive us about Iraq

In July 2003, in the week following the death of David Kelly, a reader contacted the New Statesman and suggested that the media were missing the obvious. The Commons foreign affairs committee had just cleared the government of "sexing up" the September 2002 dossier on Iraqi weapons of mass destruction - a claim, first made by Andrew Gilligan on the BBC's Today programme, for which Dr Kelly may or may not have been the source.

Our caller pointed out that although the Commons committee had said it was satisfied the "first" draft dossier, produced on 10 September for a meeting of the Joint Intelligence Committee (JIC), was the unspun work of intelligence, it had missed the true significance of a meeting the day before, chaired by Alastair Campbell.

Our caller was Chris Ames, whose name will for ever be etched on the memory of all those in government, particularly in the Foreign Office, who have resisted making public what has become known as the Williams draft (after John Williams, the Foreign Office press off More @ New Sicer who wrote it). Using the Freedom of Information Act, Ames has doggedly pursued the evidence that he believed would show that the September dossier was the work not of intelligence experts, but of spin doctors whose intention was to "sex up" the known intelligence.

From denying that the document existed, to seeking to have it withheld because publication threatened government confidentiality, to claiming that the Williams draft was an uncommissioned activity by a bored press officer (who just happened to come up with conclusions similar to those of the JIC), the government has ducked and dived and done its utmost to obstruct Ames in his pursuit of the truth.

Now, almost five years after he first contacted us, Ames's efforts have borne fruit. On 18 February, just two days before the deadline set by the Information Tribunal, the Foreign Office released the Williams draft.

Interpretations of its contents will differ, but on many counts the document speaks for itself. From it we learn that the draft was, without question, intended as part of a process of producing a dossier that would persuade the British people and parliament of the case for war. And, importantly, it shows us how much of the final dossier was the work of a spin doctor. Let's not forget that the Blair government lied repeatedly about this. The draft also reveals the extent to which Williams reworded and rewrote - and occasionally invented - intelligence assessments that were later presented to the public as the work of intelligence experts and "judgements of the JIC".
