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. Parliament was recalled on the same day to discuss the contents of the document. The paper was part of an ongoing investigation by the government into weapons of mass destruction (WMD) in Iraq, which ultimately led to the invasion of Iraq six months later. It contained a number of allegations according to which Iraq also possessed WMD, including chemical weapons and biological weapons. The dossier even alleged that Iraq had reconstituted its nuclear weapons programme.
