Deceptive opus, a cod TV programme (8)
I believe the answer is:
docusoap
'tv programme' is the definition.
(I've seen this before)
'deceptive opus a cod' is the wordplay.
'deceptive' indicates an anagram.
'opus'+'a'+'cod'='opusacod'
'opusacod' is an anagram of 'DOCUSOAP'.
(Other definitions for docusoap that I've seen before include "reality TV programme" , "TV series about people over a period" , "Television programme based on reality" .)
