All opponants of this Labour government will now need to be adamantine in their discipline this afternoon.
The disgraceful intervention by the poisonous figure of Lord Mandelson is a deliberate attempt to pour petrol on the flames of justified indignation over the detention and arrest of Damian Green MP.
To accuse those who are already extremely angry at the contempt of Parliament that the executive has shown of being "self-serving" is outrageous. It is also a deliberate attempt to wind up the opposition and ensure that the effectiveness of their attack on the partisan and incompetent Mr Speaker Martin is blunted.
It is a classic of the Mandelsonian oeuvre of political wickedness.
I think the agenda of the Conservatives and Liberal Democrats and those Labour MPs who are also deeply concerned about what has happened needs to be to protect Parliament above all else.
After that, if the Speaker is culpable, then he must face severe censure and consider his position.
As for the contemptible Mandelson- revenge is a dish best served ice cold.
