What stature does the House have now?

Word is that Michael Martin has hit the roof today. He was informed about the Sergeant-At-Arms’ (deplorable) decision to let anti-terror police forage through Damian Green’s office (I gather they’re still happily at work stripping his constituency office bare). As Speaker, he had to be informed but did not have to give his permission. The Sergeant-At-Arms did. I suspect Martin didn’t take in the gravity of the situation until last night, and the full constitutional implications of this will now have dawned on him. Why were counter-terror police involved in a common law offence? We don’t know. It does seem that neither Gordon Brown nor any minister was informed, which is in itself incredible. This raises deep questions about the nature of democracy in Britain, and about the stature of the House of Parliament which Martin is supposed to defend. Woeful.
