Left over in seaport abroad (2,5)

I believe the answer is:

to spare

'left over' is the definition.
(I've seen this before)

'seaport abroad' is the wordplay.
'abroad' is an anagram indicator.
'seaport' with letters rearranged gives 'TO SPARE'.

'in' acts as a link.

(Another definition for to spare that I've seen is " Left over".)

I've seen this clue in The Telegraph.
