Ming Campbell, PI

Presumably because all the real politicians are busy doing whatever the hell they do to kill time before they retire/lose an election, there's an interesting choice to head up the investigation into the Damian Green fiasco:

Sir Menzies Campbell is to chair an inquiry into the police raid on the Commons office of Tory MP Damian Green.

The former Lib Dem leader will review how the Commons authorities deal with search requests from the police.

So, the least charismatic politician since Michael Foot - a man so wet he couldn't even lead the wettest party in British Politics - is now heading up an investigation into the police. Unless he suddenly grows a spine, I think it is pretty safe to say that this won't be the most demanding or rigorous of investigations. Even with the likes of Howard and Blunkett - both mentalist ex-Home Secretaries - won't be able to compensate for the stuttering old man in charge of the inquiry. 

Governments can, of course, cripple these sort of investigations through a process of slow attrition. Clearly the government can't be bothered to do that in this case. Instead, they've hobbled this inquiry from the outset by putting a man who is just not up to the job in charge. As far as I can see, Ming the Merciful in charge is just one step away from not bothering in the first place.
