Club where British judge has gone dancing (8)
I believe the answer is:
bludgeon
'club' is the definition.
(both can mean a heavy weapon)
'british judge has gone dancing' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'judge' becomes 'lud' (I've seen this in other clues).
'has' says to put letters next to each other.
'dancing' indicates an anagram.
'gone' anagrammed gives 'geon'.
'b'+'lud'+'geon'='BLUDGEON'
'where' acts as a link.
(Other definitions for bludgeon that I've seen before include "Beat repeatedly with a heavy object" , "Club used maliciously" , "Bully; heavy weapon" , "Short stick with thickened end as weapon" , "Stick or club with a heavy end" .)
