State agents must arrest a married bloke (8)
I believe the answer is:
cambodia
'state' is the definition.
(Cambodia is an example)
'agents must arrest a married bloke' is the wordplay.
'agents' becomes 'cia'.
'must arrest' is an insertion indicator.
'married' becomes 'm'.
'bloke' becomes 'bod' (I've seen this in other clues**).
'a'+'m'+'bod'='ambod'
'cia' placed around 'ambod' is 'CAMBODIA'.
(Other definitions for cambodia that I've seen before include "Oriental country" , "SW Asian state" , "SE Asian nation" , "Kampuchea before 1975" , "Country, part of Indochina under French rule until 1953" .)
