We’ve been asked to believe that Ed Miliband “forgot” to mention the budget deficit in front of his party faithful gathered in Manchester last week. I’m sorry but I just don’t buy it. Sure, he stood up and spoke without notes for just over an hour. Any self-respecting member of a local amateur dramatics society can do that. Pretty much anyone who cares deeply about a significant subject – the future of your country, for instance, and why you’re the person to run it – should be able to talk without notes for an hour. And, even without a script, you don’t “forget” to include the most important part of your speech.
