Tony Benn, Hutchinson, £20
When Tony Benn left parliament in 2001 after 50 years service as an MP, he followed his late wife Caroline's advice and famously announced that he was doing so to "spend more time on politics".
As we all know by now, he wasn't kidding. His diaries of the period 2001-2007, extracts from which have just been published, are a record of political struggle in the front line, not of a placid retirement. Indeed, no serving MP - George Galloway and Jeremy Corbyn being the two exceptions - could produce a similar story of campaigning endeavour over these tumultuous years.
