It's all part of Blair's trying to distract the country from what a lying bastard he is.
He's just had his "Investiigation into Iraq" which states that the reports were a pack of lies based on dubious or questionable "evidence" plus stuff which was just "made up", then presented in a "sexed-up" speech by Blair. It states that major mistakes were made at all points of the process, but for some unfathomable reason "Nobody was to blame...."
BOLLOCKS!
Nobody believes the conclusions, which are totally at odds with the actual "findings".
Blair and Bush think that if they cry wolf (or terrorist conspiracy) long and loud enough, the Country will believe them - Isn't that pretty much what Adolph Hitler did with Jews?
QUack!
