The Chilcot Inquiry formally began its public hearings last week after being officially launched in July. So-called because it is being lead by Sir John Chilcot, a retired civil servant, this is the fourth inquiry into the Iraq conflict, following most notably the Butler Report of 2004 and the Hutton Report in 2003. The purpose of Chilcot is to “examine the United Kingdom’s involvement in Iraq, including the way decisions were made and actions taken, to establish as accurately and reliably as possible what happened, and to identify lessons that can be learned”.
