Accomplished team leader exposed to the public (5)
I believe the answer is:
overt
'the public' is the definition.
(both can mean well-known or unconcealed)
'accomplished team leader exposed' is the wordplay.
'accomplished' becomes 'over' (I've seen this before).
'team leader' becomes 'captain' (I've seen this in another clue).
'exposed' indicates the central letters (outside letters removed).
The central letter of 'captain' is 't'.
'over'+'t'='OVERT'
'to' acts as a link.
(Other definitions for overt that I've seen before include "Done or shown openly" , "Clear" , "Not concealed - public" , "Open,up front" , "____ is able to be seen" .)
