Interviewer: pay for her revised, and victory claimed! (5,7)
I believe the answer is:
oprah winfrey
'interviewer' is the definition.
(US chat show host)
'pay for her revised and victory claimed' is the wordplay.
I cannot quite understand how this works, but
'her' could be 'rey' and 'rey' is present in the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is present in the answer.
This may be the basis of clue (or it may be nonsense).
(Other definitions for oprah winfrey that I've seen before include "American chat show host" , "Chat show queen" , "Talk show host - if narrow hype (anag)" .)
