Betrayed; flogged (4)
I believe the answer is:
sold
I believe this clue is a double definition.
'betrayed' is the first definition.
('sell' can be a synonym of 'betray')
'flogged' is the second definition.
(flog can mean to sell)
(Other definitions for sold that I've seen before include "Exchanged for money" , "Disposed of to a purchaser" , "Marketed" , "Disposed of for money" , "Vended" .)
