It's all in the eyes, the snarl, the twist of the face.

It was Harriet Harman who exposed the depth of David Miliband's resentment and anger.

What kind of man would not applaud his brother when he has just delivered the most important speech of his life? It would be fair to ask the question, if your brother doesn't support you, who would? In this case the answer was Harriet, who Ed Miliband worked for as an aid, making her tea and looking for her coat only a few years ago and who will now be her boss - when David Miliband asked her  "why are you clapping" she answered in a way which should have made him feel very ashamed, "because he's the leader and I support him". She could have added  "because he's your brother and you should support him".
