Quotes from John Chilcot

The scale of the U.K. effort in post-conflict Iraq never matched the scale of the challenge.

We have concluded that the U.K. chose to join the invasion of Iraq before the peaceful options for disarmament had been exhausted. Military action at that time was not a last resort.

Blair overestimated his ability to influence U.S. decisions on Iraq.

The people of Iraq have suffered greatly.

The judgements about the severity of the threat posed by Iraq's weapons of a mass destruction - WMD - were presented with a certainty that was not justified.

Planning and preparations for Iraq after Saddam Hussein were wholly inadequate.

The U.K.'s relationship with the U.S. has proved strong enough over time to bear the weight of honest disagreement. It does not require unconditional support where our interests or judgements differ.

Despite explicit warnings, the consequences of the invasion were underestimated.

We are not a court - not a judge or jury at work - but we've tried to apply the highest possible standards of rigorous analysis to the evidence where we make a criticism.

In practice, the U.K.'s most consistent strategic objective in relation to Iraq was to reduce the level of its deployed forces.

Saddam Hussein was undoubtedly a brutal dictator who had attacked Iraq's neighbours, repressed and killed many of his own people, and was in violation of obligations imposed by the U.N. Security Council.

The U.K. military role in Iraq ended a very long way from success.
