Hurry back, seizing government vehicle (6,3)
I believe the answer is:
estate car
'vehicle' is the definition.
(estate car is a kind of vehicle)
'hurry back seizing government' is the wordplay.
'hurry' becomes 'race' (synonyms).
'back' shows that the letters should be reversed in order.
'seizing' means one lot of letters goes inside another.
'government' becomes 'state' (the state can mean government authority).
'race' backwards is 'ecar'.
'ecar' going around 'state' is 'ESTATE CAR'.
(Other definitions for estate car that I've seen before include "Vehicle with five doors" , "Motor vehicle" , "Vehicle with large area for goods" , "Brake" , "Spacious vehicle" .)
