Take over job centre in close settlement (8)
I believe the answer is:
colonise
'take over' is the definition.
('take over'->'colonize' is in my internal thesaurus and 'ize'->'ise')
'job centre in close settlement' is the wordplay.
'centre' indicates the central letters.
'settlement' indicates an anagram.
The middle of 'job' is 'o'.
'o'+'in'+'close'='oinclose'
'oinclose' anagrammed gives 'COLONISE'.
(Other definitions for colonise that I've seen before include "Populate, settle" , "Establish a state in conquered territory" , "Form a settlement in a foreign country" .)
