Who's the trouble maker then?

So who's been plotting to oust GORDON BROWN via email? BEEB political Nick Robinson knows, but didn't want to say on Today programme. Sky News suspect it is Charles Clarke, the staunch Blairite and foe to GORDON. But that is rumour. Could the trouble maker be a Brownite closer to home?..Remember the saying in hit mob film The Godfather, 'keep your friends close, your enemies closer'....
