Despite all protestations, the Labour leadership contest is shaping up to be another Blairite / Brownite battle.

Unity at the top of the Conservative Party between Cameron and Osborne has ensured that the Cabinet speaks as one (at least before Europe really takes hold). For Labour, the schism between Blair and Brown damaged it post 1997 and continues to damage it.

Labour knows that the electorate do not vote for a divided party, they learnt from their bitter experiences of the late 1970s / early 1980s. Yet, they seem likely to repeat these mistakes.

It seems that the Blairites remain bitter over David Miliband not winning last time so don't want the same thing to happen again. But the more they intervene, the more prominent the splits appear.

The candidates themselves need to do all they can to heal the apparent divides. If they don't take action then the media will continue to talk about it.
