http://nma.tv/ Ed Miliband, look out! Your elder brother is out for revenge. David is still bitter about losing the Labour party leadership and he's plotting a comeback. David has publicly denied he is planning to overthrow his brother. However, a new book says the two have rarely spoken since the leadership election. The family is also split. The Milibands' mother backed Ed over David. The brothers' wives also don't get along. Can Ed see off the challenge from his brother?
