Oh well, it probably doesn't matter as John Lanchester nailed the result back on May 6th:
As is well known, it was decided a long time ago that the new leader will be a Miliband. It is less well known that in addition to the two Milibands we know about and show no signs of warming to, the party has several other Milibands in reserve. Fenton Miliband is one. He worked for Goldman Sachs, made a lot of money then had a moment of moral revelation and went off to work for the World Bank, then founded a non-profit to study the work of other non-profits in the developing world. His strengths are compassion and maths but focus groups dislike his beard. Another strong choice is Sholto Miliband. He has a beautiful singing voice and was given his own think-tank as a christening present. His special area is Scandinavian health care, and he is so popular in Norway that they named a fjord after him. Foreigners and working-class people have been shown to be reassured by him in statistically measurable ways.
There are plenty more Milibands where they came from. They are made in a lab. It took a while to perfect the process and some of the early prototypes were hideous, unelectable mutants. Most of them were melted down and used for parts, but one escaped and by the time he had been caught he had already found a job working for Gordon Brown and was building a power base in the party, so it was too late. The prototype was called ‘Ed Balls’ but in private the Milibands refer to him as ‘Igor’.
