KEY POINTS:
The British Government's case for going to war in Iraq has been torn apart by the publication of previously suppressed evidence that Prime Minister Tony Blair lied about Saddam Hussein's weapons of mass destruction.
An attack on Blair's justification by Carne Ross, Britain's key negotiator at the United Nations, has been under wraps because he was threatened with being charged with breaching the Official Secrets Act.
Ross, 40, makes it clear Blair must have known Saddam Hussein possessed no WMDs. 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".
He also reveals British officials warned US diplomats that bringing down the Iraqi dictator would lead to chaos.
"I remember on several occasions the UK team stating this view in terms during our discussions with the US (who agreed)."
He claims "inertia" in the Foreign Office and the "inattention of key ministers" combined to stop Britain carrying out any sustained attempt to address sanction-busting by Iraq, an approach which could have provided an alternative to war.
The Foreign Office had attempted to prevent the evidence being made public, but it has been published by the Commons Select Committee on Foreign Affairs after MPs sought assurances it would not breach the Official Secrets Act.
Ross told the inquiry "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.
Ross' evidence directly challenges assertions by Blair that the war was legally justified because Saddam possessed WMDs which could be "activated" within 45 minutes and posed a threat to British interests.
