Iraq`s Weapons of Mass Destruction: The Assessment of the British Government, also known as the September Dossier, was a document published by the British government on 24 September 2002 on the same day of a recall of Parliament to discuss the contents of the document. The paper was part of an ongoing investigation by the government into weapons of mass destruction in Iraq, which ultimately led to the 2003 invasion of Iraq. It contained a number of allegations according to which Iraq also possessed weapons of mass destruction (WMD), including chemical weapons and biological weapons. The dossier even alleged that Iraq had reconstituted its nuclear weapons programme. Without exception, all of the allegations included within the September Dossier have been since proven to be false, as shown by the Iraq Survey Group.
