Tony Blair overstated the threat posed by Saddam Hussein, sent ill-prepared troops into battle and had "wholly inadequate" plans for the aftermath, the UK's Iraq War inquiry has said.
Chairman Sir John Chilcot said the 2003 invasion was not the "last resort" action presented to MPs and the public.
There was no "imminent threat" from Saddam - and the intelligence case was "not justified", he said.
Mr Blair apologised for any mistakes made but not the decision to go to war.
The report, which has taken seven years, is on the Iraq Inquiry website.
