### Clue: Loyalty may be late in following year (6)
### Answer: FEALTY 
 ### Explanation: Definition: Loyalty
  Anagram(*may be*) of *LATE* in FY(*$$f$$ollowing $$y$$ear*, I think that's what the setter intended, though I'm not familiar with it.  I know of fiscal, financial and even full year; and don't ask about FY in texting or Internet chat). 
Defn:  Fidelity,*loyalty* a vassal swears to a lord.
