Sort of programme producing a comedy turn? (11)
I believe the answer is:
documentary
'sort of programme' is the definition.
(documentary is a type of TV programme)
'producing a comedy turn?' is the wordplay.
'producing' indicates an anagram.
'a'+'comedy'+'turn'='acomedyturn'
'acomedyturn' is an anagram of 'DOCUMENTARY'.
(Other definitions for documentary that I've seen before include "on paper?" , "Factual TV programme" , "Factual programme or film" .)
