Caught topless move at liberal club (6)
I believe the answer is:
cudgel
'club' is the definition.
(cudgel is a kind of club)
'caught topless move at liberal' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'topless' means to remove the first letter.
'move' becomes 'budge' (budging is a kind of moving).
'at' means one lot of letters go next to another.
'liberal' becomes 'l' (abbreviation).
'budge' with its initial letter taken off is 'udge'.
'c'+'udge'+'l'='CUDGEL'
(Other definitions for cudgel that I've seen before include "Club used for hitting people" , "Truncheon-like weapon" , "Short thick stick used as weapon" , "A ruffian's club" , "brain" .)
