He was in my view right to exonerate the Government. And the BBC were certainly not to blame for Kelly's death, whatever their other shortcomings may have been - although Hutton does not get to the bottom of "the BBC Problem", either.  Nor was the MoD responsible, whatever the modalities of the public "exposure" - which David Kelly knew would happen, and which evidently did not unduly disturb him.  Nor was the frightful spat between Downing Street and the BBC even a contributing factor to his death.

The truth is that David Kelly died at his own hand because he could not live with what he had himself done, instigated.  With the Gilligan interview, he had clearly breached his own conditions of employment, in the most dramatic manner, and not for the first time.  Lord Hutton proposes no explanation of that.  Kelly was clearly an anguished and worried man - and a number of personal, family and possibly religious reasons have been assigned for this.  I suspect that a thorough study of those reasons would not have made happy reading for his family.

Lord Hutton was asked to investigate "the circumstances of Dr Kelly's death".  In one sense, Lord Hutton went much further than he need have done (e.g. in "clearing" John Scarlett).  And he was unduly harsh on the BBC, who had nothing whatever to do with Dr Kelly's death.  And yet he threw very little light on what really drove this distinguished scientist to take his own life.  Indeed, in several respects, I find his perceptions of Kelly shallow and inadequate.

• No doubt someone, somewhere is already working on The Life and Death of Dr David Kelly.  I will certainly read it, when it is published - in the hope it will tell me much more than Lord Hutton has been able to do.
