Bankrupt the French business (6)
I believe the answer is:
bustle
'business' is the definition.
'bankrupt the french' is the wordplay.
'bankrupt' becomes 'bust' (I've seen this before).
'the french' becomes 'le'.
'bust'+'le'='BUSTLE'
(Other definitions for bustle that I've seen before include "Hurry, scramble" , "Attachment to a Victorian woman" , "Busy oneself noisily about the former feature of women's dress" , "Hurly-burly" , "Victorian fashion" .)
