Some discredit her in government for being indecisive (9)
I believe the answer is:
dithering
'being indecisive' is the definition.
(I've seen this before)
'some discredit her in government' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'DITHERING' is hidden in the letters of 'discredit her in government'.
'for' acts as a link.
(Other definitions for dithering that I've seen before include "Flapping, hesitating" , "in a tizzy" , "Being indecisive" .)
