I'm sure you knew this post was coming. But any classicist reading Ed Miliband's first speech to conference will have instantly gone back to some good Roman precedents.
There was the new leader talking about his solid family life, not completely dishing his predecessors (he is partly dependent on them after all), but trying to put a bit of clear blue water between them and him: a new deal...new generation, who's in, who's out. (Here was the man who wrote the Labour manifesto, remember, now carefully rubbishing it!)
New Roman emperors were often in the same position, so not surprisingly they said much the same thing. That's what "succession" is all about -- a careful negotiation between past and present, to the advantage of the new order.
