Followers reunite abroad (7)
I believe the answer is:
retinue
'followers' is the definition.
(retinue can mean an important person's followers)
'reunite abroad' is the wordplay.
'abroad' is an anagram indicator.
'reunite' is an anagram of 'RETINUE'.
(Other definitions for retinue that I've seen before include "Group around VIP" , "Body of followers" , "Train, following" , "Body of attendants" , "Cortege" .)
