Some dissembling and hiding political leader (6)
I believe the answer is:
gandhi
'leader' is the definition.
(Gandhi is an example)
'some dissembling and hiding political' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'GANDHI' can be found hidden inside 'dissembling and hiding political'.
(Other definitions for gandhi that I've seen before include "Indian spinner" , "Indian political dynasty" , "film epic" , "Indira, Rajiv or Sonia" , "Indian nationalist and spiritual leader" .)
