Advise governing body to be outspoken (7)
I believe the answer is:
counsel
'advise' is the definition.
(I know that advise can be written as counsel)
'governing body to be outspoken' is the wordplay.
'governing body' becomes 'council' (I've seen this before).
'to be outspoken' shows a homophone (sound like).
'council' is a homophone of 'COUNSEL'.
(Other definitions for counsel that I've seen before include "kept by the uncommunicative" , "Advice; barrister" , "Recommend - barrister" , "Legal advice" , "Legal adviser" .)
