I had a phone call this morning from someone who wanted to know how I thought Harriet Harmon compared with Gordon Brown.
A rather risky question under the current circumstances and having never heard of this individual I naturally attempted to determine precisely who he was before answering it.
He wouldn't say and eventually gave up when I persisted.
Obviously this was someone 'testing the water' to see how much support Harman might have amongst the CLPs in advance of the party conference later this month.
The question is, was this one of Harman's supporters or Gordo's blackshirts?
