Blair blocked Cabinet from hearing legal advice on Iraq MPs demanded an emergency recall of the Chilcot inquiry last night after new revelations that Tony Blair blocked the Government's most senior lawyer from explaining to Cabinet the legality of the war in Iraq. According to the newly published full version of Alastair Campbell's diaries, the Attorney General Lord Goldsmith wanted to "put the reality" to cabinet ministers that there was a case against, as well as for, military action in March 2003. But, according to his former spin doctor, the then Prime Minister feared that the legal opinion was too "nuanced" and would allow the war's ministerial critics Robin Cook and Clare Short to say that the case had not been made. The disclosure is significant because, while it has long been suspected that Mr Blair and his inner circle put pressure on Lord Goldsmith to change his legal advice, this is the first evidence that the PM actively blocked the Cabinet from hearing the full details of the case for war. MPs from all parties urged Sir John Chilcot, who has finished taking evidence and is now preparing his report into the Iraq war, to reconvene a special session to hear from Mr Blair, Mr Campbell and Lord Goldsmith. The former Liberal Democrat leader Sir Menzies Campbell said: "According to the diaries, Tony Blair was determined that the decision should not rest with the Cabinet and overruled his Attorney General. Sofa government prevailed at the expense of constitutional requirements. The diaries prove that once a decision to go to war against Iraq had been taken, intelligence and legal advice was manipulated to support that decision. Lord Goldsmith presented a longer legal opinion to Mr Blair on 7 March 2003 in which he said he believed there was a "reasonable case" in favour of military action, but that "there was also a case to be made the other way." According to Mr Campbell's diaries, Lord Goldsmith warned Mr Blair that he did not want the Prime Minister to "present it too positively" in favour of military action because there was a "case to be made the other way." Mr Campbell wrote: "TB also made it clear he did not particularly want Goldsmith to launch a detailed discussion at Cabinet, though it would have to happen at some time, and ministers would want to cross-examine. With the mood as it was, and with Robin [Cook] and Clare [Short] operating as they were, he knew if there was any nuance at all, they would be straight out saying the advice was that it was not legal, the AG was casting doubt on the legal basis for war. Peter Goldsmith was clear that though a lot depended on what happened, he was casting doubt in some circumstances and if Cabinet had to approve the policy of going to war, he had to be able to put the reality to them. But Mr Campbell added that this was blocked by Mr Blair and his gatekeeper, Sally Morgan, during a meeting of Mr Blair and his closest aides on 11 March: "Sally said it was for TB to speak to Cabinet, and act on the AG's advice. He would simply say the advice said there was a reasonable case. Following the 11 March meeting, Lord Goldsmith produced a new, one-page legal opinion which put the "reasonable case" for war - which was discussed at Cabinet and used in Parliament to justify military action. In his own memoir, A Journey, Mr Blair did not reveal details of how he tried to block Lord Goldsmith. He said only that the Attorney General had "set out the arguments for and against and on balance came out in favour." When he gave evidence to the Chilcot inquiry in January 2010, Lord Goldsmith was asked by inquiry panel member Sir Roderic Lyne whether anyone asked him to "restrict what you said to Cabinet to the fairly limited terms in which you presented this to Cabinet." Lord Goldsmith replied: "No." Sir Menzies added: "There seems to be a substantial difference between the contents of the diaries and the evidence given to the Chilcot inquiry, and the inquiry would be well advised to reconvene itself." Last night Clare Short said she was not surprised that Mr Blair had been "deceitful" in presenting the case for war. Peter Kilfoyle, a minister in the Blair government, also called for the Chilcot inquiry to be recalled. There is a straightforward contradiction between the two positions and it needs to be corroborated. The Conservative MP Patrick Mercer said: "New facts have come to light and this makes me question whether we know enough about the then Prime Minister's attitude that justified the war." Mr Campbell said last night: "Peter Goldsmith's legal opinion is in the public domain and it was no secret he had concerns at various points. This is entirely consistent with what he and Tony Blair said to the Chilcot inquiry. Blair's road to war July 2002: Blair tells select committee "no decisions have been taken about military action." Military planning commenced in February. 24 September 2002: Downing Street "dodgy" dossier. It "established beyond doubt" Saddam has chemical and biological weapons, Blair writes. 15 January 2003: Tells MPs that there were circumstances in which second UN resolution was "not necessary." But the day before he had been advised that UN Security Council resolution 1441 was not enough on its own to justify force against Iraq. 11 Jan 2004: Asked on BBC Breakfast with Frost if he was wrong about WMD: "I don't know." 28 Sept 2004: Blair says: "I can apologise for the information being wrong but I can never apologise, sincerely at least, for removing Saddam." 1 May 2005: Leaked memo suggested that Blair was looking at ways to justify war with Iraq in July 2002, something he denies to the BBC.
