"My decision to support military action in respect of Iraq was the most difficult decision I have ever faced in my life," he wrote. "I was also fully aware that my support for military action was critical. If I had refused that, the UK's participation in the military action would not, in practice, have been possible. There almost certainly would have been no majority either in cabinet or in the Commons."He went on to say he had made a choice to support Blair, adding: "I have never backed away from it, and I do not intend to do so, and fully accept the responsibilities which flow from that. I believed at the time, and I still believe, that we made the best judgments we could have done in the circumstances."
