In answer to the original question, I'm not convinced that the answer is a move to the left. At least not the economic left. However much I feel that the polls played a part in exaggerating the scale of Labour's loss, the fact is that they were never going to win and this is because the message, or at least the leadership delivering it, were far from convincing. The economy failed spectacularly at the end of their term and yet Labour (or, perhaps more accurately, the Unions) decided to stick with essentially the same economic team at the top. The two Eds had at various times been advisers to Gordon Brown, which is a far from promising start. Perhaps now, with Ed Miliband resigning as Leader and Ed Balls not even in parliament, they have the chance to find a fresh leadership who can probably do a lot better even if selling essentially the same message as in 2015.
