Easily bribed (5)
I believe the answer is:
venal
'easily bribed' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for venal that I've seen before include "Corruptible" , "Corrupt, dishonest" , "Influenced by bribery, corrupt" , "Capable of being corrupted" , "Open to bribes" .)
