The Iraq Inquiry, also referred to as the Chilcot Inquiry after its chairman, Sir John Chilcot, is a British public inquiry into the nation's role in the Iraq War. The inquiry was announced on 15 June 2009, with an initial announcement that proceedings would take place in private, a decision which was subsequently reversed after receiving criticism in the media and the House of Commons

On 20 January 2015, Sir John Chilcot wrote to the Prime Minister to update him on the progress of the Inquiry.  The letter reports very substantial progress.  Sir John writes that the process of giving individuals an opportunity to respond to provisional criticism in the Inquiry's draft report - known as Maxwellisation - is taking place.  The letter concluded that there is no realistic prospect of delivering the report of the Inquiry to the Prime Minister before the May General Election.
