Discharged newspaperman involving an exploit (7)

I believe the answer is:

egested

'discharged' is the definition.
(egesting is a kind of discharging)

'newspaperman involving an exploit' is the wordplay.
'newspaperman' becomes 'ed'.
'involving' means one lot of letters goes inside another.
'an exploit' becomes 'geste' (I've seen this before).
'ed' placed around 'geste' is 'EGESTED'.

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