After a seven-year wait, and half a decade late, the report into the Iraq War has finally been published. But grieving families, campaigners and politicians alike feel many unknowns remain about what the future holds for Tony Blair, those who were affected by the invasion, and the Iraqi people.
In the meantime, here are the questions that we can answer so far...
What is the immediate fallout following the report's publication?
Initial statements have been made by some of the key figures, including Blair - who led the 2003 invasion of Iraq as Prime Minister - accepting responsibility for mistakes, but saying decisions were taken in "good faith".
David Cameron, who voted for war 13 years ago, said: "Members on all sides who voted for military action will have to take our fair share of the responsibility."
Sir John Chilcot, author of the report, said the Government "failed" in certain aspects.
Can Blair be tried for war crimes?
There is currently no involvement by UK police, but organisations including CND and the Stop The War Coalition have long campaigned for the former premier to be tried for war crimes, describing him as a murderer.
The fact that the Chilcot Report did not confirm the legality of military action leaves the issue open, particularly as the author found the circumstances in which the government formed a legal basis for war were "far from satisfactory".
It may be that families of Iraq war victims seek private prosecutions against the former prime minster.
How likely is it that private prosecutions will go ahead?
Lawyers for those families have said it is too early to tell whether this will happen or not.
What has this done to Blair's reputation?
If there was any doubt before the inquiry about his legacy as prime minister, the Chilcot report has cemented it.
The introduction of the minimum wage, the Good Friday Agreement, three consecutive general election wins - all these will largely fade into obscurity. Blair will be known simply by the mention of "Iraq".
And the Labour Party?
MPs are divided. Embattled leader Jeremy Corbyn - a staunch anti-war campaigner - claimed MPs were "misled" over the basis for going to war, despite not mentioning his predecessor by name.
But Corbyn, believed to be on the cusp of facing a leadership challenge, was heckled by his own MPs as he gave his response to the report.
What impact did the invasion have on Iraq?
Dr Lina Khatib, head of the Middle East and North Africa programme at think-tank Chatham House, said we are now living with the "global consequences" of war.
She said: "The Islamic State (IS) and the present conflicts in Iraq and Syria are part of the legacy of the invasion of Iraq, and the repercussions are being felt worldwide through IS terrorist attacks and the waves of migrants from Syria and Iraq heading to Europe."
Will the report have an impact on Iraq?
It is unlikely. Just days ago, 175 people were killed in Baghdad as the Muslim holy month of Ramadan came to a bloody conclusion in one of the deadliest series of attacks in the country for years.
Khatib said: "The Chilcot report points out the mistakes of the past, but in doing so what it says is ultimately not new because Iraq as well as the international community have been living with the impact of those mistakes for 13 years."
What does Iraq need?
Experts say the answer is a stabilisation plan - one that goes beyond technical military assistance and pays serious attention to good governance as well as to the need for a new social contract between Iraqi citizens and the state that fully guarantees their rights.
