David Christopher Kelly, CMG (14 May 1944 – 17 July 2003) was a British scientist and authority on biological warfare, employed by the British Ministry of Defence, and formerly a United Nations weapons inspector in Iraq. He came to public attention in July 2003 when an unauthorised discussion he had off the record with BBC journalist Andrew Gilligan about the British government's dossier on weapons of mass destruction in Iraq was cited by Gilligan and led to a major controversy. Kelly's name became known to the media as Gilligan's source and he was called to appear on 15 July before the parliamentary foreign affairs select committee investigating the issues Gilligan had reported. Kelly was questioned aggressively about his actions. He was found dead two days later.
