Move abroad -- good to get away somewhere in the Gulf? (7)
I believe the answer is:
emirate
'somewhere in the gulf?' is the definition.
(eg the United Arab Emirates in Persian Gulf region)
'move abroad good to get away' is the wordplay.
'move abroad' becomes 'emigrate' (I've seen this before).
'good' becomes 'g' (abbreviation).
'to get away' suggests deleting specific letters.
'emigrate' with 'g' taken away is 'EMIRATE'.
(Other definitions for emirate that I've seen before include "Go abroad" , "Team ire (anag.)" , "Arab territory" , "Foreign office" , "Arab land" .)
