I know that the right kind of leader for the Labour Party is a desiccated calculating machine who must not in any way permit himself to be swayed by indignation. If he sees suffering, privation or injustice he must not allow it to move him, for that would be evidence of the lack of proper education or of absence of self-control. He must speak in calm and objective accents and talk about a dying child in the same way as he would about the pieces inside an internal combustion engine.
