Stabbed in the back, but who had the knife?

IS it possible Trevor Sargent is at the receiving end of a ‘touché’ knife in the back after what happened to Willie O’Dea?

I wonder who within the cabinet would have access to information that would do Sargent down?

Stranger things have happened when governments enter the scorched earth phase of decline? Is there anything more distasteful than fools falling out?
