Just about the only truly memorable phrase uttered by Edward Heath, the Tory Prime Minister in the 1970s, was his description of Tiny Rowland, the boss of Lonhro (who also, for a time, owned the Observer) as “the unpleasant and unacceptable face of capitalism”. (Rowland famously replied that he would not want to be its acceptable face, which was quite a good riposte.) But Tiny has long since passed to his reward. The Digger and his spawn are proving worthy inheritors of his title.
