It started in 2009 and has been trundling along with brief spouts of media interest ever since with a brief recess to "avoid influencing the general election".  Of course the Inquiry's actual powers are very limited.  Documents can be withheld from it on security grounds and no one gives evidence on oath.   None-the-less almost all the oral evidence has been given in public and even some of the non-public hearings are available to read as transcriptions so it is possible for observers to write their own reports.  So for some time we toyed with the idea of a Pear Shaped Inquiry Enquiry and this page is the result.
If you want a sensible analysis instead try the Iraq Inquiry Digest

All public inquires are really an exercise in getting embarrassing data into the public domain as slowly as possible given the speed with which it is otherwise likely to leak there. In general they tend to exist to make sure that if the truth cannot be whitewashed then it can at least be spread about fairly equally.  So sporadic bursts of interest come and go but no overall cohesive story is transmitted to the public.  Of course now all the evidence has been submitted there will soon be a final report but Whitehall still has powers of veto.  So below is the little sense we could make of it.   After considering reproducing transcripts might be slightly visually and mentally dull we decided instead to opt for animation using the Xtranormal web platform which is still a bit dull as all the 3D animated characters speak in monotone and look a bit jerky ...unlike the real video footage of the Iraq Inquiry which shows a number of people who are monotonous and a number who act like ... We couldn't help but notice that almost all the interviewees are men but fortunately we are not bright enough to draw any conclusions from this.

The Inquiry stats with Christopher Meyer the United Kingdom Ambassador in Washington throughout

While Sir David Manning ponders on how George W Bush's administration was so bitterly divided amongst its self that they didn't even know what George W Bush would say to the UN before he said it to the UN ....

Major General Graham Binns General Officer Commanding Multi-National Division South East, Aug 2007 – Feb 2008 talks about exactly how the UK forces supported the Iraqi General Mohan in Basra who commanded using a mobile phone...

Vice Admiral Charles Style talks about exactly how many military operations the British Armed Forces are designed to undertake and sustain at any one time and how running the Afghanistan and Iraq operations in parallel caused some resourcing issues.

Lord Turnbull Cabinet Secretary, 2002 – 2005 described the generation of the Iraq War dossier as process of "granny's footsteps".

Jack Straw says that while the wider issues were discussed you cant just go around trusting the Cabinet with information.  There are 27 or 28 of them.  Far too many.  Just him, Geoff Hoon, Jack Straw, Gordon Brown, Tony Blair, Alastair Campbell and erm...?

claims he did not know a misleading impression of the 45 minute claim had been circulating in the press as he was too busy and out the country in Kiev...

...with so few people being allowed to know anything Mr Hoon simply had too much to do.  Mr Hoon claims he only really understood what the issue was afterwards when he saw an episode of Panorama.

To be fair the size of the Cabinet has always been controversial.   And it has been growing in size since 1900.   In the 1950s Harold McMillan actually had to make the table larger due to the increase of people in the government...

The cabinet is technically a sub-committee of the Privy Council that was naturally formed when the Privy Council became too large to make decisions like which of the King's wives should have their head cut off this week.  The machination of "sofa government" is simply the subconscious reiteration of the basic laws of optimum committee size.  Huge volumes of research are done all the time into optimum committee sizes.  The most often cited guesses for the best size are between 5 and 7 people.  Which is fine as long as you're not discussing taking an entire nation to war...?  Of course the other problem with the Cabinet is while it's too large to make fast decisions it's also too small to have the authority of the House of Commons ...so is it a decision making policy committee or a policy rubber stamp?
Your guess is as good as mine.
