Seven years since it launched, the Chilcot Inquiry will on Wednesday (6 July) publish findings into the build-up to the Iraq war, the conflict itself and its chaotic aftermath. The report will be published at 11am before its architect, Sir John Chilcot, makes a statement.
Weighing in at a mighty 2.6m words, the report spans summer 2001 to the end of July 2009 and draws upon tens of thousands of documents – including correspondence between then Prime Minister Tony Blair and US counterpart President George Bush - and hundreds of hours of witness testimony.
