The long-awaited report into the Iraq war will be published on Wednesday, July 6, an inquiry spokesman has said.
Security checks on the 2.6 million word report have been completed without the need for any redactions.
The date of publication was agreed by the Inquiry's head, Sir John Chilcot and David Cameron.
In a letter to the Prime Minister, Sir John said: "National security checking of the Inquiry's report has now been completed, without the need for any redactions to appear in the text. I am grateful for the speed with which it was accomplished."
He added: "This will allow suitable time for the Inquiry to prepare the 2.6 million word report for publication, including final proof reading, formatting, printing and the steps required for electronic publication."
