I believe the answer is:

retinue

I'm a little stuck... Click here to teach me more about this clue!

'the following' is the definition.
(I've seen this before)

're-unite' is the wordplay.
're-unite' anagrams to 'RETINUE'.
However, I am unsure how this is indicated.

Can you help me to learn more?

(Other definitions for retinue that I've seen before include "Body of followers" , "Reunite (anag) - group of servants" , "Group around VIP" , "Entourage, followers" , "Group of followers" .)

I've seen this clue in The Irish News.
