Objector turned up in remote protection (9)
I believe the answer is:
disputant
'objector' is the definition.
(thesaurus)
'turned up in remote protection' is the wordplay.
'turned' is a reversal indicator.
'in' means one lot of letters goes inside another.
'remote protection' becomes 'distant' (I can't justify this - if you can you should believe this answer much more).
'up' reversed gives 'pu'.
'pu' placed within 'distant' is 'DISPUTANT'.
Can you help me to learn more?
(Other definitions for disputant that I've seen before include "Striker, perhaps" , "One who argues" .)
