Play Andrew Porter? (6)
I believe the answer is:
warden
'porter?' is the definition.
(thesaurus)
'play andrew' is the wordplay.
'play' indicates an anagram.
'andrew' with letters rearranged gives 'WARDEN'.
(Other definitions for warden that I've seen before include "Official in charge of prisoners" , "Andrew, strangely, is in prison" , "Chief official in charge of a prison" , "Official with supervisory duties, as in relation to a church" , "Governor of the Cinque Ports has this title" .)
