Secret agent resolved to be in the limelight (6,5)
I believe the answer is:
centre stage
'be in the limelight' is the definition.
(I've seen this before)
'secret agent resolved' is the wordplay.
'resolved' indicates anagramming the letters.
'secret'+'agent'='secretagent'
'secretagent' anagrammed gives 'CENTRE STAGE'.
'to' acts as a link.
(Other definitions for centre stage that I've seen before include "In the spotlight" , "Main point of attention" , "Main focus of attention - secret agent (anag)" , "(Position of) main focus of attention" , "Most prominent position" .)
