The Prime Minister is thought to have agreed to write his memoirs for an advance of £4 million. That is quite a gamble for any publisher. A Pretty Straight Kind of Guy (or whatever it is called) will have to sell mountains of copies if the money is to be recouped.
For that, we will need revelations that clear up some of the genuine mysteries surrounding Tony Blair, as opposed to the usual score-settling that characterises politicians' memoirs. So, instead of another behind-the-scenes account of the Iraq controversy, let us have the true story of young Anthony's attempt to stow away on a flight to the West Indies (which no one else remembers) or more reminiscences of watching Jackie Milburn (who retired when Mr Blair was four).
It is a good thing for the Prime Minister that advances are non-returnable: even if the book bombs, he will effectively have earned £400,000 for every year he was in office. Who knows? With that sort of money in the bank, the Blairs may even decide to pay for their own holidays.
The Blairs pay for their own holidays? A bit optimistic, surely.
