I apologise to Forum readers. It had not occurred to me that it was not obvious, but it is apparent from the posts after Justin's that it should have done.
I was referring to Chris Fegan.
Chris has a lot of experience of municipal election campaigns. He has served as a Labour councillor on Chelmsford Borough Council and on Essex County Council, both of which are predominantly Conservative.
I don't know for certain that it was he to whom Malcolm was referring, but he fits the description better than any of the other people mentioned.
