David Miliband has won his second Labour leadership "primary" in Edinburgh East, securing 39 per cent of the vote. Ed Miliband came second with 34 per cent, and Andy Burnham was the only other candidate to make it into double figures.
This vote was held by the Labour MP for Edinburgh East, Sheila Gilmore, as a way of determining her constituents' intentions before casting her own vote. A similar ballot has also been held in Bassetlaw , and resulted in the local MP, John Mann, switching his support from Ed Miliband (whom he initially nominated) to David after 50.3 per cent of those balloted opted for the elder brother. David also scored well on second preferences , a good sign going into the ballot itself. Another primary  is planned for Dudley North.
These so-called primaries will have little meaning in the long run, but in August's political drought they provide something of an indication of how the candidates are perceived. As Mehdi Hasan pointed out  weeks ago, the leadership contest is very much a two-horse race.
More interesting, perhaps, is Ed Balls's mediocre showing in these ballots. He came a poor third in Bassetlaw and has now been beaten into fourth place by Andy Burnham in Edinburgh East. Tthis is only going to prompt further discussion about whether Balls will withdraw from the race  and back one of the Miliband brothers, perhaps as a way of securing the post of shadow chancellor, as Jim Pickard  over at FT Westminster suggests.
All we can really infer from these primaries, then, is that neither Miliband has opened up a particularly strong lead yet, and that the other three candidates have yet to mount a serious challenge.
