For readers of certain publications, these are not new. Lord Goldsmith, the Attorney General, gave a written submission to the PM which almost certainly said that to go to war with Iraq was illegal. He never gave another. The Guardian discovered that two close colleagues of Mr Blair and members of the number 10 inner circle, Lord Falconer and Baroness Morgan, wrote a summary of what is referred to as Lord Goldsmith's advice on the eve of the war, which was the document distributed before parliament voted.
The deputy legal adviser at the Foreign Office, Elizabeth Wilmshurst, resigned before the war saying that an attack had no legal legitimacy and would amount to a "crime of aggression".
The Guardian has been pressing for some time for the release of the Attorney General's original submission to be released under the Freedom of Information Act and they have now been joined by most of the media and the opposition parties.
Others as diverse as Clare Short and John Major have also called for the release of the documents. The government has refused, claiming that it would not be in the public interest.
