Not wanting queen repeatedly to be the one presenting (7)
I believe the answer is:
offerer
'the one presenting' is the definition.
(I've seen this before)
'not wanting queen repeatedly' is the wordplay.
'not wanting' becomes 'off' (eg someone no longer eating something is 'off' it).
'queen' becomes 'er' (abbreviation for Elizabeth Regina).
'repeatedly' says to double the letters.
'er' duplicated is 'erer'.
'off'+'erer'='OFFERER'
'to be' acts as a link.
(Other definitions for offerer that I've seen before include "One presenting something for acceptance" , "One proposing, bidding or presenting" , "I propose" .)
