Allow me to add my piece of (unsolicited but free) advice: don’t be Mr Angry. People want to like you; they want to feel that you can be trusted. They know they don’t like Labour. They know that the country needs change. But they are not yet sure you represent a benign form of change. How bizarre it may seem for politicos, when you attack Gordon Brown too ferociously, the electorate sympathises with him. When you disparage Nick Clegg, they think you look like a bully.
So don’t be angry. Be firm, be clear, show frustration on behalf of an impoverished nation, but be positive, show some levity. As Elizabeth Kenny said: “He who angers you conquers you.” And you don’t want that to happen, do you?
