Corrupt party is a game (8)
I believe the answer is:
baseball
'game' is the definition.
(baseball is a kind of game)
'corrupt party' is the wordplay.
'corrupt' becomes 'base'.
'party' becomes 'ball' (ball is a kind of party).
'base'+'ball'='BASEBALL'
'is a' is the link.
(Other definitions for baseball that I've seen before include "Mainly North American game" , "Popular American sport" , "American team game" , "Game played in a strangely able labs" , "Nine-a-side game" .)
