This could get interesting.
Heidi Alexander, Shadow Health secretary, has quit the Shadow Cabinet.
Her reasons are a bit bemusing - apparently Labour should be gearing up to fight an 'increasingly rightwing and inward looking Conservative Party.' And she thinks this end can be achieved by precipitating a Blairite coup, leading to an extended civil war within Labour. Seems like it won't just be the Conservatives that will be 'inward looking' over the next few months.
I've always thought the British Labour Party was far more stable and sane than the antipodean ones, which seem to swap leaders every five minutes and are engaged in eternal factional wars.
Clearly, they've just been saving it all up for a massive, massive dust up.
