Clip of confidence trick by political party is not new - it's the one where the wrongdoers get suspended (8)
I believe the answer is:
scaffold
'the one where the wrongdoers get suspended' is the definition.
I can't judge whether this defines the answer.
'clip of confidence trick by political party is not new' is the wordplay.
'clip of' means to remove the last letter (clip can mean a shortening of something).
'confidence trick' becomes 'scam' (I've seen this before).
'by' means one lot of letters go next to another.
'political party' becomes 'ff' (I've seen this in other clues. I am not sure about the 'political' bit.).
'is not new' becomes 'old' ('old' is the opposite to 'new').
'scam' with its final letter taken off is 'sca'.
'sca'+'ff'+'old'='SCAFFOLD'
'it's' is the link.
Can you help me to learn more?
(Other definitions for scaffold that I've seen before include "Old platform for hangings" , "Temporary erection for workmen - gallows" , "Metal framework or raised platform" , "Place of execution" , "Platform on which criminals were executed" .)
