Renounce international body for example (5)
I believe the answer is:
unsay
'renounce' is the definition.
(I know that unsay is a type of renounce)
'international body for example' is the wordplay.
'international body' becomes 'UN' (short for United Nations).
'for example' becomes 'say' ('say' can be used to introduce an example).
'un'+'say'='UNSAY'
(Other definitions for unsay that I've seen before include "Recall" , "Take back (words)" .)
