From the UK's Independent:
The Government's case for going to war in Iraq has been torn apart by the publication of previously suppressed evidence that Tony Blair lied over Saddam Hussein's weapons of mass destruction.
A devastating attack on Mr Blair's justification for military action by Carne Ross, Britain's key negotiator at the UN, has been kept under wraps until now because he was threatened with being charged with breaching the Official Secrets Act.
In the testimony revealed today Mr Ross, 40, who helped negotiate several UN security resolutions on Iraq, makes it clear that Mr Blair must have known Saddam Hussein possessed no weapons of mass destruction. He said that during his posting to the UN, "at no time did HMG [Her Majesty's Government] assess that Iraq's WMD (or any other capability) posed a threat to the UK or its interests."
Mr Ross revealed it was a commonly held view among British officials dealing with Iraq that any threat by Saddam Hussein had been "effectively contained".
He also reveals that British officials warned US diplomats that bringing down the Iraqi dictator would lead to the chaos the world has since witnessed. "I remember on several occasions the UK team stating this view in terms during our discussions with the US (who agreed)," he said.
"At the same time, we would frequently argue when the US raised the subject, that 'regime change' was inadvisable, primarily on the grounds that Iraq would collapse into chaos."
He claims "inertia" in the Foreign Office and the "inattention of key ministers" combined to stop the UK carrying out any co-ordinated and sustained attempt to address sanction-busting by Iraq, an approach which could have provided an alternative to war.
Mr Ross delivered the evidence to the Butler inquiry which investigated intelligence blunders in the run-up to the conflict.
The Foreign Office had attempted to prevent the evidence being made public, but it has now been published by the Commons Select Committee on Foreign Affairs after MPs sought assurances from the Foreign Office that it would not breach the Official Secrets Act.
It shows Mr Ross told the inquiry, chaired by Lord Butler, "there was no intelligence evidence of significant holdings of CW [chemical warfare], BW [biological warfare] or nuclear material" held by the Iraqi dictator before the invasion. "There was, moreover, no intelligence or assessment during my time in the job that Iraq had any intention to launch an attack against its neighbours or the UK or the US," he added.
