Withdrawal concerning trustee battle (10)

I believe the answer is:

retraction

'withdrawal' is the definition.
(withdrawing or retracting something)

'concerning trustee battle' is the wordplay.
'concerning' becomes 're' (both can mean on a particular topic).
'trustee' becomes 'tr' (abbreviation).
'battle' becomes 'action' (military action).
're'+'tr'+'action'='RETRACTION'

(Another definition for retraction that I've seen is " Withdrawal of a statement".)

I've seen this clue in the Sydney Morning Herald.
