Exaggerated account discredited (9)
I believe the answer is:
overdrawn
This clue is a double definition.
'exaggerated' is the first definition.
('overdraw' can be a synonym of 'exaggerate')
'account discredited' is the second definition.
(I've seen this before)
(Other definitions for overdrawn that I've seen before include "Cartoonishly exaggerated" , "lacking a healthy balance?" , "is no longer credited" , "bust?" , "got into debt" .)
