Probably only political obsessives managed to stick with yesterday's extended edition of Newsnight to the bitter end, but for those that did, there was a real treat in store.
Jeremy Paxman was chairing a studio discussion featuring Howard, Polly Toynbee, Charles Kennedy, Alan Milburn, David Hare and Alastair Campbell. Towards the end, the talk turned to Tony Blair's style of government and the impact of spin and sleaze.
Howard recalled that in the days when the young Tony Blair used to shadow him at Employment and the Home Office, he found him at all times to be absolutely straight and honest.
Then, looking across at Campbell, he declared: "I believe the man sitting there is who's responsible for what changed." Campbell had no response to it other than to accuse Howard of being a sore loser.
Howard's right, of course. Blair must bear the final responsibility as the man who employed him, but it was Campbell whose bullying of journalists and civil servants in the cause of news management did more than anything else to demean our political culture during the Blair years.
And of course, it was Campbell who wanted to get Dr David Kelly's name out in the open in order to "fuck Gilligan," part of the chain of events that ultimately destroyed the public's trust in Mr Blair.
The Guardian's Will Woodward has written a piece in today's Blair Resignation Supplement (not online as far as I can see) the gist of which is that Tony Blair would not have been the same force without Alastair Campbell.
Will is a nice guy who has already gone far in the Lobby and will go further, but he's wrong on this one. Without the baleful influence of Alastair Campbell, Tony Blair might have been a great Prime Minister.
