'Some years ago, in my essay ‘No Secret Selves?’, I attempted to develop a typology for the personal writings of politicians. I have since tried to refine that typology, though I still remain unhappy with the nomenclature. I would now suggest a fivefold typology as follows: (1) personalised policy essay; (2) political autobiography; (3) political memoir; (4) politician’s autobiography; and (5) political diary. As references in this workshop suggest that some of you have read that essay, I will spend little time on those categories that have remained unchanged and will concentrate on the refinements and more particularly on the category of the political diary.'
