Port links abandoned helper with arrogance (4-4,4)

I believe the answer is:

left-hand side

'port' is the definition.
(thesaurus)

'abandoned helper with arrogance' is the wordplay.
'abandoned' becomes 'left' (leave can mean to abandon).
'helper' becomes 'hand' (I've seen this in another clue).
'with' is a charade indicator (letters next to each other).
'arrogance' becomes 'side' (I've seen this before).
'left'+'hand'+'side'='LEFT-HAND SIDE'

'links' acts as a link.

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