Ongoing struggle, administering East Sussex town! (7,6)
I believe the answer is:
running battle
'administering east sussex town' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'ongoing struggle' is the wordplay.
'ongoing' becomes 'running' (synonyms).
'struggle' becomes 'battle' (a struggle or ordeal might be called a battle).
'running'+'battle'='RUNNING BATTLE'
Can you help me to learn more?
(Other definitions for running battle that I've seen before include "drawn-out dispute" , "indecisive skirmish" , "Moving engagement" , "Fight carrying on continuously" , "Continuing skirmish" .)
