"Could it be the folks not agreeing with the next venture into another regime (Tehran) have declined to go to the party under duress?"
No, it's almost certainly not related to any foreign policy at all. There was always going to be a reshuffle at this point, Blair is looking like a total lame duck at the moment and the last couple of weeks have seen a number of embarrasing incidents, so he needed to look like he was doing something.
I understand but am not sure I agree. looking at which offices were "cleaned out" makes me suspicious. I have no experience with the British system but Blair does not strike me as a person who ducks, he appears (Yea I know) to be one to take the punch and keep on keeping on. Here in the good old US of A. I agree with Murphys rules of government.

Any agency expands to fit all space available... So that more space is always required
