Reportedly goes for a cunning plan (6)
I believe the answer is:
wheeze
'for a cunning plan' is the definition.
(I've seen this before)
'reportedly goes' is the wordplay.
'reportedly' shows a homophone (sound like).
'goes' becomes 'wees' (go can mean to urinate).
'wees' sounds like 'WHEEZE'.
(Other definitions for wheeze that I've seen before include "Audible inspiration" , "Breathe with hoarse sound, or a clever idea" , "Clever scheme; sound asthmatic" , "Breathe noisily; clever dodge" , "Breathe with hoarse whistling sound" .)
