Challenging type seen in different locations around clubs (10)
I believe the answer is:
iconoclast
'challenging type' is the definition.
(someone challenging traditional symbols)
'different locations around clubs' is the wordplay.
'different' indicates anagramming the letters.
'around' is an insertion indicator.
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'locations' with letters rearranged gives 'iconolast'.
'iconolast' enclosing 'c' is 'ICONOCLAST'.
'seen in' is the link.
(Other definitions for iconoclast that I've seen before include "Rebel" , "Unorthodox thinker" , "heretic" , "Challenging type" , "Debunker of reputations" .)
