This is a list of witnesses of the Iraq Inquiry, sorted chronologically, who have given testimony to the Iraq Inquiry, a British public inquiry into the United Kingdom's role in the Iraq War. The inquiry, chaired by career civil servant Sir John Chilcot, commenced on 24 November 2009. From November to December 2009, the witnesses were primarily civil servants and military officials including Tim Cross and Sir Peter Ricketts. Following a Christmas break, the inquiry heard predominantly from politicians, including former cabinet ministers, including Gordon Brown as well as Tony Blair, Prime Minister at the time of the invasion. The Iraq Inquiry adjourned in March 2010 to avoid influencing the general election campaign and the last witnesses gave testimony in June 2011. On 6 July 2016 Sir John Chilcot published the report, more than seven years after the inquiry was announced.
Ricketts gave evidence regarding the buildup to the Iraq War in which he claimed there was a "palpable" threat that Saddam Hussein could have acquired weapons of mass destruction, though he went on to say that nobody in the British government was advocating Hussein's removal at that point. He also told the inquiry that the British government had been reviewing its policies on Iraq as early as 2001, in anticipation of the Bush administration taking power in the USA.
Patey offered similar testimony on attitudes towards "regime change", though added that the 11 September attacks "added an edge" to concerns over Iraq's acquisition of weapons of mass destruction
Wood would also give evidence in January 2010
Ehrman gave evidence that intelligence in 2003 suggested that Iraq may not have weapons of mass destruction and that Tony Blair, prime minister of the day had been aware of the evidence when he presented the "September Dossier" to Parliament. However, Ehrman went on to defend the invasion, claiming that Iraq had "flouted" United Nations resolutions.
