Nick Cohen has written a superb article for Standpoint magazine this month. You can read the online version of it here.
He uses his experience and actual first hand evidence of Brown's henchmen at work to illustrate how Brown got to the top and the underhand tactics he has used since getting there. It makes it clear that the McBride/Draper Sleazegate scandal was far from a one-off and is fact symptomatic of how people close to the Prime Minister operate.
Probably the best MSM article I have read this year so far.
