Lewis, you mention the Chilcot report on the war.
We have here in Oz Royal commisions to look into such events and are I would assume similar to this rteport.
The problem with all is the terms of reference those looking into the matter are working with.
Depending on those terms any result can emerge and it may not be the full story or even the truth in full.
But from what we saw of Blair from afa,r he was a slime ball with very little ethics and with a greater interest in self promotion and advantage that any I can recall over recent times.
