Well done for Charlie's predecessor (5)
I believe the answer is:
bravo
I believe this is a double definition.
'well done' is the first definition.
(I've seen this before)
'charlie's predecessor' is the second definition.
(I've seen this in another clue)
'for' is the link.
(Other definitions for bravo that I've seen before include "Jolly good" , "Three cheers" , "Shout of approval" , "Good job!: international radio code word" , "Hurrah!" .)
