I CAN not understand why anyone would want to buy the Diaries of Alistair Campbell when he has admitted that they contain nothing of any use to David Cameron nor to any other political party.

They also say almost nothing about Gordon Brown and unless they tell the truth, the whole truth and nothing but the truth, the whole exercise is pointless. As he was master of spin, there is little reason to believe much of what is noted down in this book, which will bring in a tidy sum of money for AC Esq.
