Vote in some uppity bankrupt celebrity (5)
I believe the answer is:
elect
'vote in' is the definition.
(I've seen this before)
'some uppity bankrupt celebrity' is the wordplay.
'uppity' says the letters should be written backwards.
'some' indicates a hidden word (some of the parts of the word are used).
'tcele' is hidden within 'bankrupt celebrity'.
'tcele' backwards is 'ELECT'.
(Other definitions for elect that I've seen before include "Choose; singled out" , "Waiting to get into office" , "Chosen - to vote" , "Choose by voting" , "Opt for; chosen" .)
