Harry Enfield met corruption (10)
I believe the answer is:
defilement
'corruption' is the definition.
(thesaurus)
'harry enfield met' is the wordplay.
'harry' indicates anagramming the letters (harry can mean to attack or spoil).
'enfield'+'met'='enfieldmet'
'enfieldmet' anagrammed gives 'DEFILEMENT'.
(Other definitions for defilement that I've seen before include "Pollution" , "Desecration" .)
