Secrecy and less than full cooperation on the part of the Blair government, as reported in yesterday's Guardian:

The government withheld from the Hutton inquiry pages from one draft of its dossier setting out the dangers Iraq's alleged weapons of mass destruction (WMD) posed, it was revealed yesterday....

Yesterday the Hutton inquiry said that the government had not sent it three pages from the executive summary issued in Tony Blair's name of the September 16 version, drawn up eight days before the dossier was made public....

...The Cabinet Office did not respond when asked to comment about the missing dossier pages, nor did Downing Street when asked if it would release the witness statements of Mr Blair, Mr Campbell and other officials.

Apparently it's true that poodles resemble their masters.
