One of those doing the numbers for consigliere dismissing e coli (6)
I believe the answer is:
singer
'one' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for singer that I've seen before include "Coventry car firm" , "Diva perhaps" , "choirboy?" , "Member of a choir" , "Warbler" .)
