Confidence of a revolutionary faced with censure (7)
I believe the answer is:
panache
'confidence' is the definition.
(I have seen 'Flamboyant confidence ' mean 'panache' so perhaps 'confidence' could also mean 'panache')
'a revolutionary faced with censure' is the wordplay.
'revolutionary' becomes 'che' (Che Guevara the Marxist revolutionary).
'faced with' says to put letters next to each other.
'censure' becomes 'pan'.
'a'+'che'='ache'
'ache' after 'pan' is 'PANACHE'.
'of' is the link.
(Other definitions for panache that I've seen before include "flourish" , "Flamboyance - style" , "Dash and verve" , "stylish carriage" , "Grand manner, theatricality" .)
