A supporter of privilege (3)

I believe the answer is:

leg

'a supporter' is the definition.
(I've seen this in another clue)

'of privilege' is the wordplay.
'of' indicates the answer is hidden within the clue.
'LEG' is hidden within 'privilege'.

(Other definitions for leg that I've seen before include "Lower limb" , "Run < on" , "prop" , "Support; cricket side" , "Limb; stage" .)

I've seen this clue in the Evening Standard.
