Today's media has been verging on the ridiculous in the prominence and credibility they give to what are little more than footnotes in the various biographies that are being hawked around at the moment. (How many times did Lord Levy drop in 'As I say in my book' during his TV interview today?)
On the subject of Lord L's latest intervention - Gordon, to my recollection, didn't run the 2005 General Election campaign (although he was one of the main architects of the 1997 and 2001 landslides). Alan Milburn was put in charge in 2005, and Gordon was only brought in at the last moment to rescue things when it all went pear-shaped. So Levy is wrong.
