Scottish port getting round embargo (4)
I believe the answer is:
oban
'scottish port' is the definition.
(I've seen this before)
'round embargo' is the wordplay.
'round' becomes 'o' (round can mean a round object).
'embargo' becomes 'ban' (a ban on trade).
'o'+'ban'='OBAN'
'getting' is the link.
(Other definitions for oban that I've seen before include "small Scottish port" , "Scottish port and resort" , "port required" , "Scottish west coast resort" , "Port and holiday centre on the west coast of Scotland" .)
