Alan Johnson, MP and memoirist, in conversation with me in Dulwich on September 29 2016

Rated by certain wise heads as the Prime Minister we ought to have had circa 2009, Alan Johnson has won an alternative and arguably more gratifying distinction for himself as a bestselling and prize-winning memoirist. Following This Boy and Please, Mr Postman, he is poised to publish a third volume of life studies entitled The Long and Winding Road, this one carrying his story into the echelons of trade union leadership, election as a Labour MP and a number of stints as government minister. Johnson will be discussing his life and works with me in a special event organised by Dulwich Books at 7pm on September 29, at All Saints Church on Lovelace Road, West Dulwich.

There's a good piece in today's Financial Times by Robert Shrimley, in which Johnson is compared with the former Sunderland South MP Chris Mullin, who has also turned his hand to writing with distinction and who, like Johnson, manages the feat of being a politician who is a recognisable human being. Shrimsley credits Johnson with 'the common touch; an easy manner that belies his intelligence and his hard upbringing.' He goes on to argue:

'At a time when the public is increasingly alienated from the archetypal politician, especially those who seem to have spent their entire life in political activity, the need for able, moderate leaders with a demonstrable human touch has never been more pressing.'

I do take issue with the grounds of this so-called public 'alienation'; and I don't think politicians need to beg for their characters if they didn't happen to come from a tough and unpromising background. It's a fact, moreover, that people with the most obvious human qualities still might struggle with those aspects of political leadership that call for something of the devil's work. And it's quite clear that Alan Johnson, for his own perfectly good reasons, never really wanted to take a crack at the job of leading Labour. Still, however forlornly, I rather wish that he had - just because the road not taken might have been one of the several that could have steered us clear of our present wreckage.
