Objector in favour of examiner (9)

Ross

I believe the answer is:

protester

'objector' is the definition.
(I know that objector can be written as protester)

'in favour of examiner' is the wordplay.
'in favour of' becomes 'pro' (being pro a particular cause).
'examiner' becomes 'tester' (synonyms).
'pro'+'tester'='PROTESTER'

(Other definitions for protester that I've seen before include "Person, we hear, not content" , "Demonstrating kind" , "objector" , "I strongly object" , "Demonstrator" .)

I've seen this clue in The Daily Express.
