Spruced up politician nosily investigated coats (7)

I believe the answer is:

primped

'spruced up' is the definition.
(both can mean tidied or improved)

'politician nosily investigated coats' is the wordplay.
'politician' becomes 'MP' (Member of Parliament).
'nosily investigated' becomes 'pried' (to pry is to investigate nosily).
'coats' means one lot of letters goes inside another (inserted letters are coated in another word).
'mp' inserted inside 'pried' is 'PRIMPED'.

I've seen this clue in The Times.
