Pull out of Portugal (3)
I believe the answer is:
tug
'pull' is the definition.
(tugging is a kind of pulling)
'out of portugal' is the wordplay.
'out of' indicates a hidden word.
'TUG' is hidden within 'portugal'.
(Other definitions for tug that I've seen before include "Pull forcibly" , "Powerful boat" , "draw with some effort" , "Small ship for pulling" , "Pull like small boat" .)
