US politician’s weakness over gift I’d put in (4,9)
I believe the answer is:
vice president
'us politician's' is the definition.
(Vice President of the United States)
'weakness over gift i'd put in' is the wordplay.
'weakness' becomes 'vice' (I've seen this before).
'over' means one lot of letters go next to another.
'gift' becomes 'present' (synonyms).
'put in' means one lot of letters goes inside another.
'present' placed around 'id' is 'president'.
'vice'+'president'='VICE PRESIDENT'
(Other definitions for vice president that I've seen before include "who assists the top man?" , "senior politician" , "Number two to 46, say" , "US leader's deputy" , "Not in charge" .)
