New bugle Don wanted for club (8)
I believe the answer is:
bludgeon
'club' is the definition.
(both can mean a heavy weapon)
'new bugle don' is the wordplay.
'new' indicates anagramming the letters.
'bugle'+'don'='bugledon'
'bugledon' with letters rearranged gives 'BLUDGEON'.
'wanted for' is the link.
(Other definitions for bludgeon that I've seen before include "Stick or club with a heavy end" , "Beat repeatedly with a heavy object" , "(Beat with a) heavy stick" , "Bully; heavy weapon" , "Strike with a club" .)
