Followers of desperate mutineer, miles away (7)
I believe the answer is:
retinue
'followers' is the definition.
(thesaurus)
'desperate mutineer miles away' is the wordplay.
'desperate' is an anagram indicator (I've seen this in other clues).
'miles' becomes 'm' (common abbreviation).
'away' indicates named letters should be taken away.
'mutineer' with 'm' taken out is 'utineer'.
'utineer' is an anagram of 'RETINUE'.
'of' is the link.
(Other definitions for retinue that I've seen before include "Figure out" , "Train, following" , "Cortege" , "Group of attendants for VIP" , "Train; attendants" .)
