Reaction:Prime minister Tony Blair, responding to an inquiry into flawed British intelligence on Iraq's banned weapons, told parliament today: "No one lied."
"No one made up the intelligence. No one inserted things into the (September 2002) dossier against the advice of the intelligence services," he added.
A long-awaited report by former top civil servant Lord Butler concluded that Britain's intelligence on Iraq's armaments had "serious flaws" but apportioned no blame to any one individual, Blair or otherwise.
Mr Blair admitted it was increasingly unlikely any banned weapons would be found.
"I have to accept, as the months have passed, it seems increasingly clear that at the time of invasion Saddam did not have stockpiles of chemical or biological weapons ready to deploy," Mr Blair said.
He repeated his recent justification for war - that he genuinely thought Saddam posed a threat and the world was a safer place for his removal.
"For any mistakes made, as the report finds, in good faith I of course take full responsibility, but I cannot honestly say I believe getting rid of Saddam was a mistake at all," he said.
Before the invasion, Mr Blair argued the case for war on the basis that Baghdad had biological and chemical weapons and was prepared to use them.
The notorious UK dossier from September 2002 said some could have been fired within 45 minutes of an order to do so. Yet more than a year since Saddam Hussein was ousted, no such weapons have been found.
Lord Butler said that assertion should not have been included without heavy qualification.
But opposition leader Mr Michael Howard said Mr Blair's reputation was now shot.
"If this prime minister said war was necessary again, would the country trust him?" he asked parliament.
"Does he have any credibility left?" Mr Howard asked.
