The much-anticipated document claimed to be based on reports made by the Joint Intelligence Committee, part of the British Intelligence 'machinery'. Most of the evidence was uncredited in order to protect sources.
The press criticised the dossier on its release for its tameness and for the seeming lack of any really new evidence of import. However, two sections of the text would later become the centre of fierce debate: the allegation that Iraq had sought "significant quantities of uranium from Africa", and the claim that it was capable of deploying WMDs within 45 minutes of an order to do so.
The claim that Iraq was seeking to buy uranium from Africa was repeated in George W. Bush's State of the Union Address in January 2003. The controversial 16 words used by US President W Bush on January 28, 2003 were "The British government has learned that Saddam Hussein recently sought significant quantities of uranium from Africa."
In March, the International Atomic Energy Agency concluded that documents alleging transactions between Niger and Iraq were blatant forgeries.
However, in July, Tony Blair testified to the House of Commons Liaison Committee that the evidence the government had regards Iraq's dealings with Niger came from a separate source to the fraudulent documents.
Subsequently, CIA director, George Tenet, stated that the remarks about the link between Iraq and Niger should not have been included in the US President's speech. This followed a remark by American National Security advisor Condoleezza Rice, saying that the presence of the line in the speech showed that it had been authorised by the CIA.
The British Foreign Secretary Jack Straw later told the Foreign Affairs Select Committee (which was investigating the veracity of the claims in the dossier) that British intelligence on the matter had not been shared with the CIA, and that the statement in the dossier was based on reliable intelligence.
The 45 minute claim lies at the centre of a row between Downing Street and the BBC. On 29 May 2003, BBC defence correspondent Andrew Gilligan filed a report for BBC Radio 4's Today programme in which he stated that an unnamed source - a senior British official - had told him that the September Dossier had been "sexed up", and that the intelligence agencies were concerned about some "dubious" information contained within it - specificly the claim that Saddam Hussein could launch weapons of mass destruction within 45 minutes.
On 1 June, Gilligan expanded upon that claim in the Mail on Sunday newspaper, stating that the government's director of communications, Alastair Campbell, had been responsible for the insertion of the 45 minute claim, against the wishes of the intelligence agencies. Gilligan subsequently gave evidence before the Foreign Affairs Select Committee, as did Campbell, who denied ordering the inclusion of the claim, and demanded an apology from the BBC. He subsequently backed this demand in writing.
The BBC refused to apologise, and stood by Gilligan's story. Campbell responded angrily, with an appearance on Channel 4 News.
On 7 July the Select Committee published a report which cleared Campbell, albeit on the casting vote of the chairman. In the report, the committee stated that the 45 minute claim had been given "undue prominence".
The next day, the Ministry of Defence claimed that one of its officials (later named as Dr. David Kelly) had come forward, admitting to having discussed the matter of Iraq's weapons with Gilligan on 22 May. The BBC responded by saying that Kelly differed from Gilligan's key source in "important ways". Kelly was subsequently called before the Foreign Affairs Select Committee whose conclusion was that Kelly was being used as a scapegoat and that he had not been Gilligan's key mole.
On 17 July, Gilligan gave evidence to a private session of the Select Committee, and was subsequently criticised for not naming his source, and for changing his story. The BBC continued to stand by him.
On the same day, Kelly left his home for an area of woodland and was later found dead with his wrists slit, apparently having committed suicide.
On 20 July, Richard Sambrook, director of news at the BBC, revealed that Kelly was indeed the key source for Gilligan's report, and that the BBC had not said so before so as to protect Kelly. The BBC stressed that Gilligan's reporting accurately reflected Kelly's comments, implying that Kelly had not been entirely truthful with the Select Committee. The BBC has committed to assisting fully with the forthcoming Hutton Inquiry into Kelly's death.
