The German holding party in Africa, one providing entertainment (6)
I believe the answer is:
dancer
'one providing entertainment' is the definition.
'the german holding party in africa' is the wordplay.
'the german' becomes 'der' ('the' in German).
'holding' is an insertion indicator.
'party in africa' becomes 'anc' (African National Congress).
'der' placed around 'anc' is 'DANCER'.
(Other definitions for dancer that I've seen before include "Mover to music" , "Fred Astaire, say" , "Ballet performer" , "Terpsichorean" , "Craned (anag.)" .)
