UPDATE: bye bye to the ginger midget as well. The Cabinet's disintegrating fast - how can Gordon hope to hold it together? I suppose he can always promote a bunch of useless no-hoper sycophants into Cabinet positions and hang on until he has to call an election next year. Come to think of it, a Cabinet full of useless no-hopers wouldn't really stand out as unusual anyway.
UPDATE 2: One more resignation could finish him off? Maybe, but has the Son of the Manse so far lost the plot that he'll still refuse to go?
