I've just spent a month campaigning alongside Diane Abbott in Hackney North in a very comradely and united campaign that resulted in her doubling her majority and Labour gaining six council seats.
As you might expect, I won't personally be voting for Diane if she gets nominated to run for the Labour Leadership as we have rather different perspectives on the major issues facing the Party - though there are occasional surprising ones we agree on.
However, I think it's good that she is running and hope (though doubt) she can get the 33 MPs necessary to get nominated - we need a genuine ideological debate to take place involving candidates from all wings of the Party so that the leadership result measures opinion in the Party and gives a political mandate to whoever wins. I also agree with her point that the field needed some diversity in terms of its gender and ethnicity.
Her decision hasn't been that popular with her colleagues in the Campaign Group though. It drives a stake through any chances the "official" hard left standard-bearer John McDonnell had of collecting enough nominations.
