Seems pretty clear that the case for believing that Saddam had "Weapons of Mass Destruction" at his fingertips was hyped up, with a view to persuading wayward backbenchers to support the war.

What difference does it make if that was done at the direct request of the Government, or by agents of the Government doing what they knew was required of them?

The purpose of focussing on this non-issue was to divert attention from the real issue, and it appears that David Kelly cracked under the pressure of being used in this way. Assuming that it was in fact suicide.

The whole murky business is very reminiscent indeed of the recent TV serial State of Play.
