Staff nearly able to charge Michelle Mone, perhaps - an amoral businesswoman (9)
I believe the answer is:
profiteer
'mone perhaps an amoral businesswoman' is the definition.
I can't tell whether this definition defines the answer.
'staff nearly able to charge michelle' is the wordplay.
'staff' becomes 'rod' (both can mean a pole or stick).
'nearly' means to remove the last letter.
'able' becomes 'fit' (similar in meaning).
'to charge' means one lot of letters goes inside another (charge can mean to fill).
'michelle' becomes 'peer' (I can't justify this - if you can you should believe this answer much more).
'rod' with its final letter taken off is 'ro'.
'ro'+'fit'='rofit'
'rofit' put inside 'peer' is 'PROFITEER'.
Can you help me to learn more?
(Other definitions for profiteer that I've seen before include "Overcharge" , "One charging too much" , "Gain unfairly" , "He charges too much in times of scarcity" , "capitalist" .)
