Sir Alan is trying to outdo his namesake in writing a dairy where he is rude to just about anyone he has come into contact with.
Of course, the Mail, which adores anything like this, is searialising his tittle tattle, and rubbing its hands together with glee at how the politicians to whom it cow tows daily, are given a drubbing in indiscreet terms, which is meat and drink to most Mail readers who adores seeing their 'betters' brought down because it makes the readers feel better about being lower down the social scale, when those above them can be insulted for money.
