As stated in “The Report of the Iraq Inquiry – Executive Summary”: “810. … -Mr Brummell wrote to Mr Rycroft on 14 March:
‘It is an essential part of the legal basis for military action without a further resolution of the Security Council that there is strong evidence that Iraq has failed to comply with and co-operate fully in the implementation of resolution 1441 and has thus failed to take the final opportunity offered by the Security Council in that resolution. The Attorney General understands that it is unequivocally the Prime Minister’s view that Iraq has committed further material breaches as specified in [operative] paragraph 4 of resolution 1441, but as this is a judgment for the Prime Minister, the Attorney would be grateful for confirmation that this is the case.’ “
