It's not only Miliband who deals with difficult questions by repeating the same memorised text over and over again. I googled " Miliband loop" and almost immediately lighted on a clip of George Osbourne doing exactly the same thing. The journalists could stop the politicians using this dodge by broadcasting the interviews in full, but they don't because- well- I suppose they all went to their same schools or eat in the same restaurants or something. The journalist who outed Miliband says he did it because he felt ashamed to be part of the process. As well he might.
