Smell from chamberpot no good (4)

Ross

I believe the answer is:

pong

'smell' is the definition.
(pong can informally mean a bad smell)

'chamberpot no good' is the wordplay.
'chamberpot' becomes 'po' (old-fashioned informal term for a chamber pot).
'no good' becomes 'ng' (abbreviation).
'po'+'ng'='PONG'

'from' is the link.

(Other definitions for pong that I've seen before include "Bad smell" , "Ping's regular partner?" , "Reek" , "It may make one wrinkle nose" , "Horrid smell (informal)" .)

I've seen this clue in The Sun and The Telegraph.
