I'm told by a source in the Ed Miliband team that the brothers held several secret meetings this week, once it became clear that Ed would win. David was "unhelpful and very upset", my source says.
David will be offered the job of Shadow Chancellor, though the Ed team are not very confident that he will accept it.
One reason why the brothers were talking on the assumption of an Ed win is because Ed Miliband and his team expected a much more decisive victory. An MP in the Ed Miliband campaign tells me they had predicted exactly the PLP section vote, and quite closely the Union and Affiliates section vote, but they were disappointed with the Members section vote, as their figures had shown them winning among ordinary party members.
This might explain why several senior Ed Miliband supporters I've bumped into this evening have been looking pretty glum.
Not to have a majority or your MPs, or party members - and to depend on union votes - leaves Ed Miliband in a very exposed position.
Ironically, he'll have to spend much of the next few weeks distancing himself from the unions and showing he's not in their pocket.
