Mangle radio version of Spitting Image (7)
I believe the answer is:
wringer
'mangle' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for wringer that I've seen before include "Kitchen appliance" , "Old-fashioned clothes dryer" , "A mangle" , "trouble when put through this?" , "Old clothes dryer" .)
