Drive politician round, collecting papers (6)
I believe the answer is:
libido
'drive' is the definition.
(thesaurus)
'politician round collecting papers' is the wordplay.
'politician' becomes 'lib'.
'round' becomes 'o' (round can mean a round object**).
'collecting' means one lot of letters goes inside another.
'papers' becomes 'id' (identification papers).
'lib'+'o'='libo'
'libo' placed around 'id' is 'LIBIDO'.
(Other definitions for libido that I've seen before include "Emotional craving" , "Strong urge" , "Sexual or psychological urge" , "lust!" , "Freud's sex drive" .)
