The government official who wrote the first draft of the "dodgy dossier" that helped propel Britain into war in Iraq today admits, "We were wrong."
John Williams, a former Foreign Office aide, said last night that publication of his document would expose how members of Tony Blair's team were locked in a mindset that made military action inevitable.
On Wednesday, ministers will hit a deadline for publishing the 2002 document, after years of resistance.
The Williams draft was written in September 2002, only days after Mr Blair, then Prime Minister, announced that the Government would publish a dossier of intelligence showing that Saddam Hussein threatened the world with his weapons.
The draft was not disclosed at the Hutton inquiry into the death in 2003 of the former Iraq arms inspector David Kelly. The scientist had suggested the dossier was exaggerated to justify the UK joining the 2003 invasion.
