Former auditor reported government funds? (9)
I believe the answer is:
exchequer
'government funds?' is the definition.
(I've seen this before)
'former auditor reported' is the wordplay.
'former' becomes 'ex' (prefix meaning former or onetime).
'auditor' becomes 'checker'.
'reported' indicates a 'sounds like' (homophone) clue.
'checker' is a homophone of 'chequer'.
'ex'+'chequer'='EXCHEQUER'
(Other definitions for exchequer that I've seen before include "large supply of money" , "Treasury accounting department" , "royal treasury" , "Government funding?" , "finance department" .)
