Hedge circles complete with hedge (9)
I believe the answer is:
'hedge' is the definition.
(both can mean to delay)
'hedge circles complete with' is the wordplay.
'hedge' becomes 'stall' (both can mean to avoid giving an answer).
'circles' is an insertion indicator.
'complete' becomes 'one' (I've seen this in another clue).
'with' becomes 'w' (abbreviation).
'stall' going around 'onew' is 'STONEWALL'.
(Other definitions for stonewall that I've seen before include "delay in parliament" , "Stand firm" , "Engage in delaying tactics - General Jackson?" , "Play to defend" , "Obstruct or hinder any discussion" .)
