Brit involved with routine punishment (11)

I believe the answer is:

retribution

'punishment' is the definition.
(thesaurus)

'brit involved with routine' is the wordplay.
'involved with' indicates an anagram (involved can mean confusing or complex).
'brit' anagrammed with 'routine' can make 'RETRIBUTION'.

(Other definitions for retribution that I've seen before include "Vengeance" , "True iron bit (anag.)" .)

I've seen this clue in The Sunday Times and The Times.
